Firstly, DWM is the only window manager for x11 that needs to exist. I used i3 for the longest time, but didn't feel happy. I've tried others but nothing compares to the power and minimalism of DWM. Don't want to install the package, just compile it from source. While it takes time to understand DWM, such as patching it and understanding just a little bit of C, it is so simple and is a good base to then build up from. It doesn't come with some of the most basic features, but that is what makes it so good. It can be made and handcrafted perfectly for the user. No bloat. It is the perfect WM to pair with the Gentoo ideology. Secondly, the Everforest colorscheme. I tried it on neovim for my Macbook and fell in love with it. I used Gruvbox to start and then Kanagawa, but something about them always felt off. Everforest has become my favorite colorscheme for everything. I plan on updating my dot files finally after months of not touching them. Thirdly, Picom. The Pijulius Picom is so good and I don't know why I have never used it. On Arch I kept trying to get animations with a bunch of different forks and such but I should have just went simple and started with his. Its so easy to build and then just run picom and boom, simple but clean animations. I plan I trying to do a challenge of a year or 2 years of just Gentoo. I have really no tie to Windows now that I have pretty much given up on CoD and Destiny 2 so I can kind of dedicate my time to just Gentoo and really explore and understand it. Maybe Gentoo will become my best distro and Arch will be replaced. This will be updated soon DWM-Dots.  ( 3 min )

GitHub Homepage During my junior year studies, high concurrency processing has always been one of the technical fields I'm most interested in. While traditional multi-threading models can handle concurrent requests, they often encounter performance bottlenecks when facing large numbers of connections. Recently, I deeply studied a Rust-based web framework whose high concurrency processing capabilities gave me a completely new understanding of asynchronous programming. In my previous projects, I used thread pool-based concurrency processing models. This model allocates a thread for each request, and while implementation is simple, it has obvious scalability issues. // Traditional Java thread pool model @RestController public class TraditionalController { private final ExecutorService th…  ( 7 min )

GitHub Homepage: https://github.com/eastspire/hyperlane During my final year project on distributed systems, I encountered a fundamental challenge that shapes modern web development: how to enable efficient bidirectional communication between clients and servers. Traditional request-response patterns felt inadequate for the interactive applications we were building. My exploration of bidirectional communication led me to discover patterns that revolutionize how we think about client-server interaction. The breakthrough came when I realized that most web applications still operate under outdated communication paradigms designed for static content delivery. Modern applications require dynamic, interactive communication patterns that traditional HTTP cannot efficiently provide. My research re…  ( 8 min )

GitHub Homepage: https://github.com/eastspire/hyperlane My deep dive into context management began during a performance optimization project where I discovered that inefficient request context handling was creating memory leaks and performance bottlenecks. Traditional web frameworks often treat context as an afterthought, leading to resource waste and complex state management. This experience led me to explore how sophisticated context management can dramatically improve both performance and developer experience. The pivotal insight came when I realized that request context isn't just about passing data between functions—it's about creating an efficient, type-safe mechanism for managing the entire request lifecycle. My research revealed a framework that implements context management patter…  ( 9 min )

GitHub Homepage During my junior year studies, I have encountered many different web frameworks, from Spring Boot's "convention over configuration" to Django's "batteries included." Each framework has its unique design philosophy. Recently, I discovered an impressive web framework that adopts a completely different design philosophy—zero-dependency design. This minimalist design philosophy made me reconsider the essence of software architecture. In my previous project experience, dependency management has always been a headache.

Let me start by saying. I love Arch Linux. It's fast, easy (after RTFM), and all around my perfect distro if I need to go to something to tinker. However, I think I found my new distro to tinker with. While people go from Linux Mint to Ubuntu. I am going from Arch to Gentoo. I tried Gentoo a year or two ago, but my laptop was slow as f**k and I had no clue what I was doing or how to read the manual. I tried to install Gentoo again yesterday or the day before and installed it fairly easy. Without videos might I add, just the manual. The thing that set me off to try Gentoo again was when I was trying to make a custom kernel for Arch and was majorly failing and then I remembered that Gentoo was meant for that kind of customization. IMO, the only thing that has annoyed me about Gentoo so far is that the Firefox-esr (I should have done the binary) takes ages and I couldn't get audio to work for the life of me. I finally have it installed however and aside from my mouse buttons not working properly and I have to make a custom kernel, I have crafted the perfect system. DWM. Gentoo. Everforest. The only things that truly matter.  ( 3 min )

This post is based on Uniface Documentation 10.4 and was created with AI assistance. Hey developer community! 👋 Today we're diving into the fascinating world of Uniface trigger activation. If you've ever worked with event-driven applications, you know how complex the behind-the-scenes processes can be.

Hi everyone! I’m 18 and just finished my +2 (biology stream, no computer science). Right now, I’m thinking of learning coding seriously, improving my skills, and maybe trying for internships, freelancing, or junior roles before I go for a formal degree. My idea is to build a portfolio first and then, after gaining some practical skills and confidence, pursue a degree (either part-time, distance, or regular) so I don’t waste years without direction. But I’m a bit worried: I’d love to hear from developers who took non-traditional paths or have seen others do this. Any advice on how to plan my learning and career would mean a lot! Thank you so much for your time 🙏  ( 3 min )

Linux provides various command-line and graphical text editors for file manipulation. Common command-line editors include nano, vi/vim. These tools allow users to create, open, edit, and save files. In this practice, I will use vi because I personally prefer vi than nano To use vi Type vi and filename you want to edit Press Enter If I want to start writing or editing the contents I will first of all Press (i) insert then I will start writing or editing after which I will Press (esc) key (:) Colon (w) Write (q) Quit (!) Bang Then Press Enter That takes you back. Then if you want to see or view the contents of what you have written or edited use (cat) (cat) — Concatenate — It is used to quickly view the content of one or more files directly in the terminal, it can also be used to merge file and its contents into another file. (cat) — Concatenate- To merge and create a file and its contents into another file. echo- This is used to create a file, write a file and over write the contents in an existing file. vi Editing Commands Command Description i Insert at cursor (goes into insert mode) a Write after cursor (goes into insert mode) A Write at the end of line (goes into insert mode) ESC Terminate insert mode u Undo last change U Undo all changes to the entire line o Open a new line (goes into insert mode) dd Delete line 3dd Delete 3 lines D Delete contents of line after the cursor C Delete contents of a line after the cursor and insert new text.

In Linux, files can be viewed and inspected using various command-line tools. cat, head, tail, less, and file are commonly used for displaying file contents and determining file types.  less: View file contents interactively (scrollable).  less file.txt: Open a file for reading.  head/tail: View the start or end of a file.  head -n 10 file.txt: Show first 10 lines.  tail -f file.log: Monitor a log file in real-time.  file: Determine a file’s type.  file filename: Identify file format (e.g., text, binary).  ( 3 min )

In Linux, archiving and compression are distinct but often used together to manage files efficiently. Archiving combines multiple files and directories into a single archive file, while compression reduces the file size for storage and transfer. This will optimize costs in your company. Creating archives with tar: gzip can’t add multiple files into one archive, hence we use the tar program. c — create v — tell the program to be verbose and let us see what it is doing f — the filename of the tar file has to come after this option tar -cvf file3.txt.tar file3.txt Then to achive files and directories tar -cvf archive.tar list the files and directories Then to archive files and directories tar -cvf archive.tar list the files and directories tar xvf text.txt.tar To extract a tarred file : $ tar xvf archive.tar List the files in a tarred file Zip and unzip files (Before you do this make sure that there’s zip apt in your system) tar -czvf lesson.js.tar.zp gzip/gunzip: Compress/decompress files. gzip file.txt: Compress to file.txt.gz. gunzip file.txt.gz: Decompress. zip/unzip: Work with ZIP archives. zip archive.zip file.txt: Create a ZIP file. unzip archive.zip: Extract a ZIP file.  ( 3 min )

Wave is a language that supports inline assembly. In its current pre-beta stage, it compiles through LLVM. If this works, we might just be writing the very first line in Wave’s low-level programming history. Today, we’re going to attempt exactly that: creating a boot sector using only Wave. At the moment, Wave uses LLVM as a temporary backend. Whale — optimized specifically for Wave and free from the limitations of LLVM. Of course, before that can happen, Wave’s frontend needs to be fully developed. In a previous post, I showed how to print “Hello World” using only Wave. Typically, boot sectors and bootloaders are written in raw assembly. asm {} block, making it possible to implement a boot sector directly in Wave. The basics of Wave’s inline assembly syntax are explained in my earlier pos…  ( 4 min )

Hey everyone, Slobodan here—your friendly economics grad turned aspiring dev.In my last post, I shared the bumpy road to launching econdev.studio, complete with white screens and deployment drama. Today marks another milestone: polishing that site with the help of Grok, xAI's witty AI assistant. Unlike some of my earlier entries (which, let's be honest, felt a bit formulaic thanks to quick ChatGPT drafts), this one's infused with more personal flair, deeper tech dives, and the actual back-and-forth that made it fun. Why Grok? Well, after wrestling with code on my own, I wanted an AI that could guide me step-by-step without just spitting out generic templates. Grok felt more like a coding buddy—analyzing my files, suggesting fixes, and even cracking jokes along the way. We tackled nagging bugs like a transparent navbar, invisible particles in the hero section, overflow issues, and unclickable blog buttons. The result? A sleeker, more interactive site that's now fully live. Let's break it down, with real code snippets from our session. The Starting Point: What Was Broken? Transparent Navbar: It blended into the background, making the site look unfinished. Turns out, a missing CSS variable was the culprit. Lessons Learned: Why This Felt Different Personal reflection: As an econ guy, I love efficiency, but coding's taught me patience. Today's wins? A professional site that showcases my projects, blog, and contact form. Failures? Forgetting to clear caches—classic newbie move. But that's the journey: from frustration to "aha!" moments. If you're building your own site, try AI as a co-pilot. Tools like Grok (built by xAI) bring reasoning and humor—way beyond basic chatbots. What's Next? Thanks for reading.

Developing for the Internet of Things (IoT) often involves connecting devices that are tucked away on local networks. While AWS IoT provides a powerful platform for managing these devices, a common challenge arises when you need to expose a service running on one of them—like a web server or an API—to the public internet. This is crucial for tasks like testing webhook integrations, remote a web-based dashboard, or sharing your work with colleagues. Traditionally, getting a public URL for a device on a local network requires complex network configuration like setting up port forwarding on your router, dealing with dynamic DNS, or deploying a reverse proxy. These solutions can be time-consuming, insecure if not done correctly, and sometimes impossible if you are behind a CGNAT or corporate f…  ( 7 min )

Introduction: The Port Forwarding Wall If you've ever tried to self-host a service—be it a personal website, a game server, a private cloud, or an API for a project—you've likely encountered the term "port forwarding." It's the standard method for making a service running on your local network accessible to the wider internet. You log into your router, find the port forwarding section, and map an external port to the internal IP address and port of your local machine. But what happens when it just... doesn't work? You've followed every guide, triple-checked your settings, but your server remains invisible to the outside world. The frustrating culprit is often something you have no control over: Carrier-Grade NAT (CGNAT). CGNAT is a technology used by many Internet Service Providers (ISPs…  ( 9 min )

To switch images in desktop and mobile view using CSS media queries, you can use the following approach: HTML: CSS: .mobile-image { display: none; } @media only screen and (max-width: 768px) { .desktop-image { display: none; } .mobile-image { display: block; } } In this example, the .desktop-image is displayed by default, and the .mobile-image is hidden. When the screen width is 768px or less ( typical mobile screen width), the .desktop-image is hidden, and the .mobile-image is displayed. Alternatively, you can use the picture element and srcset attribute to achieve the same result: This approach allows the browser to choose the correct image based on the screen width, without needing to use CSS media queries. You can also use CSS background images and media queries to achieve the same result: .image-container { background-image: url('desktop-image.jpg'); } @media only screen and (max-width: 768px) { .image-container { background-image: url('mobile-image.jpg'); } } Note that the image container element should have a fixed height and width for this approach to work.  ( 3 min )

What is a Variable? A variable is a name that refers to a value stored in memory. It acts as a container to hold data that can be reused or manipulated throughout a program.

Running a web server on Red Hat Enterprise Linux (RHEL) is a common task for developers, system administrators, and businesses who rely on its stability and security. Whether you're developing an application, hosting a personal project, or setting up a testing environment, you'll often need to make your server accessible from the public internet. However, due to network security measures like firewalls and NAT, your RHEL server is typically isolated within a local network, inaccessible from the outside world. This comprehensive guide will walk you through the process of getting a secure, public URL for your RHEL server. We'll start by setting up a standard Nginx web server on RHEL. Then, we'll introduce Tunnelmole, an open-source tool that simplifies the process of creating a public endpoi…  ( 9 min )

This is my submition for Amazon Q Build Games Challenge Imagine this: It’s 2008, and I’m sitting next to my father at his new Acer Aspire laptop. The room echoes with the satisfying sounds of bouncing balls and shattering bricks as we take turns playing Jardinains!, each of us determined to beat the other’s high score. Those moments of friendly rivalry and shared laughter became some of my most treasured childhood memories. Now, as an engineering student competing in the Amazon Q Build Games Challenge, I knew exactly what I wanted to bring to life. Not just any game, but that game, the one that brought my father and me closer, and showed me how the simplest ideas can create the most unforgettable experiences.

Something wild is happening in tech right now. Meta is reportedly throwing $100 million signing bonuses at AI researchers—yes, you read that right, ONE HUNDRED MILLION DOLLARS. Meanwhile, a couple of developers in a garage somewhere are building the next billion-dollar startup with nothing but laptops. It's absolutely bonkers, and it perfectly captures the schizophrenic state of the tech industry in 2025. So what the hell does this mean for regular developers trying to figure out their careers? Let's talk about these compensation packages because, honestly, they're mind-blowing: Meta is reportedly offering some AI engineers over $2 million per year. That's not a typo. The average Meta software engineer pulls in anywhere from $205K (junior) to $3.67 million (senior principal) But here's th…  ( 7 min )

Want to convert any text into any language? Let’s create a simple Python script to do it! What We're Building Our translator will be a Python script that: Prompts the user to specify their target language Accepts text input for translation Uses OpenAI's GPT model through LangChain to perform the translation With the Artificial Intelligence APIs available today, it is incredibly simple. Instead of validating the name of the language that the user inputs, let’s leave it open-ended for some creativity. I.e., we can translate to natural language descriptions such as "Spanish," "French," or "Shakespearean English", or even “Chandler Bing” (from the TV show Friends). Prerequisites Before we dive in, you'll need: Python 3 installed on your system. This was written with 3.13. An OpenAI API …  ( 5 min )

Functional Programming (FP) is a paradigm that treats computation as the evaluation of mathematical functions. It avoids concepts of changing state and mutable data that can be unfamiliar to many imperative programmers. Haskell is a purely functional language and a great way to explore the core ideas of FP. Its syntax is expressive, and its type system enforces many of FP’s core principles. Immutability: Data is never changed once created. Pure Functions: The same input always gives the same output and has no side effects. First-Class Functions: Functions are treated like any other variable. Recursion: Loops are replaced with recursive function calls. Higher-Order Functions: Functions that take other functions as parameters or return them. add :: Int -> Int -> Int add x y = x + y This function is pure—it always returns the same output for the same inputs, and it doesn’t modify any state. Easier reasoning about code Fewer bugs due to immutability Improved modularity and reusability Even if you don’t plan to use Haskell in production, learning it can deepen your understanding of functional programming and improve your skills in other languages like JavaScript, Scala, or Rust.  ( 3 min )

Introduction Applications often require specific values that do not change at runtime. For example variables containing values such as number of months in a year, PI number, Euler number, etc. Since this values are referenced by different modules, it could be catastrophic if they're modified a thread or process is triggered. The C# language helps to avoid this situations by including constants. A constant is a value that is assigned at compile time and will never be modified at runtime, meaning it won't change for the whole application lifetime. A constant must be a declared using the const keyword and primitive types (int, bool, decimal, double, byte, char, string, etc.). Here's an example: public class MyMathClass { public const double Pi = 3.1416; } The correct way to call a co…  ( 5 min )

"We cut our JS build time from 28 seconds to 0.8—here’s how you can too." For years, Webpack and esbuild dominated frontend builds.

Hello Data Engineers 👋 I've been scouting on the internet for the best and easiest way to setup dbt Core 1.9.0 with Airflow 3.0 orchestration. I've followed through many tutorials, and most of them don't work out of the box, require fixes or version downgrades, and are broken with recent updates to Airflow and dbt. I'm here on a mission to find and document the best and easiest way for Data Engineers to run their dbt Core jobs using Airflow, that will simply work out of the box. Disclaimer: This tutorial is designed with a Postgres backend to work out of the box. But you can change the backend to any supported backend of your choice with little effort. So let's get started.

Project Overview This is a simple console-based number guessing game implemented in Python. The computer "thinks" of a random number within a specified range (1 to 100), and the player's goal is to guess that number. The game provides hints ("Too high!" or "Too low!") after each guess, helping the player narrow down the possibilities. The game tracks and displays the number of attempts it took to guess the correct number. Random Number Generation: The computer selects a random integer between 1 and 100 (inclusive) as the secret number. Interactive Guessing: Players can repeatedly enter their guesses. Hints System: Provides feedback to the player after each guess, indicating whether their guess was too high or too low. Guess Counter: Keeps track of the number of attempts the player makes.…  ( 5 min )

This post is my submission for DEV Education Track: Build Apps with Google AI Studio. I built a Mood-based Travel Poster Generator, an AI-powered app that creates unique travel posters based on the user's current mood. I used this prompt in Google AI Studio: "Build a web app that take the user current mood. Based on the mood, the app suggests a matching travel destination and generates a travel poster using Imagen. The image should reflect both the emotion and the destination’s essence (e.g., 'melancholic' → rainy Venice; 'curious' → ancient ruins in Peru). Include a 'Regenerate Poster' button to create a new variation. Add a simple UI with a text input and a dropdown of mood presets." This project was a great exercise in blending creativity and technical design. I learned how to: Structure prompts for more stylized image outputs Use the Imagen API effectively for emotion-to-visual mapping Thanks to Google AI Studio and DEV for making this learning experience fun and creative!  ( 3 min )

Understanding Beginner Debugger for Beginners Have you ever written code that just… doesn’t work? It’s a frustrating experience, but a completely normal part of being a programmer! That’s where debuggers come in. Learning to use a debugger is one of the most important skills you can develop as a new programmer. It’s a tool that helps you step through your code line by line, inspect variables, and understand exactly what’s happening – and why it’s not doing what you expect. In fact, being able to confidently talk about debugging techniques is a common question in technical interviews! Think of a debugger like being a detective investigating a crime. The "crime" is your code not working as expected. Instead of looking for clues at a crime scene, you're looking at the values of variabl…  ( 6 min )

Bulk GoHighLevel Email Template Deletion Tool Clean up your GHL subaccounts in seconds — no code or backend needed. GoHighLevel (GHL) is a great platform for email marketing and automation. But there's one big problem — you can’t delete email templates in bulk. If you have 50, 100, or 300+ templates, you have to remove them one by one. That takes a lot of time. So I built a simple tool that helps you fetch, select, and delete multiple email templates with just a few clicks. Fetch all email templates from your GHL subaccount Show each template’s name, ID, and last updated time Let you select multiple templates Delete them in bulk using GoHighLevel’s official API Works entirely in your browser — no server or database needed Before using the tool, you will need: This is your Subaccount ID in GoHighLevel. You can find it in your URL when inside a subaccount. Go to: Settings → API → Create Private Key Make sure to give the key these permissions: View Templates Add/Edit/Update/Delete Templates Download or open the tool in your browser (you’ll get the link from the GitHub repo below). Enter your Location ID and Private Integration Key Click “Fetch” The tool will show all templates Uncheck the ones you want to keep Click “Delete from GHL” to start deletion Keep at least a 2-second delay between each delete for safe API calls The tool runs in your browser. Your token is used locally, so make sure you’re using it on a trusted computer. Once deleted, templates are permanently removed from your GHL account. 👉 View Source Code on GitHub This tool is made for GHL users who want to save time and clean up their email templates quickly.

From my observation, C developers have a wide range of opportunities, including embedded systems, operating systems, and hardware-level programming. However, in the job market, many tend to gravitate towards game development, as game engines still heavily rely on C or C++. When it comes to writing libraries, C is often not the first choice. This is primarily because developing comprehensive, clean libraries in C requires significant skill, patience, and time, especially due to the complexities of low-level memory management. While some developers create their own libraries for personal use, few share them publicly. C remains an excellent language, but as technology evolves, it may no longer be viewed as a “modern” language and might gradually fade from widespread use. The rapid rise of AI-…  ( 4 min )

Everyone wants instant success—but here’s the reality: We live in a world chasing instant results. Start today, expect success tomorrow. But real growth? It doesn’t work like that. Success is rarely the result of one big action. It comes from small efforts repeated over time. It builds momentum, even when no one’s watching It strengthens discipline and focus It creates opportunities that random effort can’t The truth is: results are often delayed. That’s why most people quit too soon. Think of every small action as a drop of water. One drop seems pointless. But if you keep going, the glass eventually overflows. That’s how consistency works—slow at first, then unstoppable. You don’t need to be the fastest or the best. You just need to keep showing up. Because in the end, it’s not talent or luck that wins. It’s consistency.  ( 3 min )

One of the most important things I’ve learned during my internship is that user experience is built in the details. Today’s challenge? Search and filtering for legal cases inside Lura. Lawyers work with hundreds of cases. Scrolling manually isn’t practical. They need fast, flexible ways to find what they’re looking for. Our job as developers is to create features that feel simple — even if they're not. 🧠 Why It Matters Search by title (e.g., “Doe vs Smith”) Tag-based filtering (e.g., “Criminal”, “Pending”) Workspace-scoped results (can’t show data across teams) Without this, the app feels clunky.

Recently at work, I had a task of developing and deploying an internal tool/application which basically lets us test certain playback stream URLs (DASH, HLS etc.) on Smart TVs using ShakaPlayer with Widevine DRM encryption. So this application was deployed on one of our internal remote servers. There are a couple of other applications as well which are deployed on that remote server, but they had a simpler single-click deployment (pretty convenient 🙂). As for this particular application, we had to deploy it manually by transferring the files from our local machine to the remote server (actually better because I got to learn something new 🤓). The reason I shared the above story with you is that due to the above task, I got introduced to the SCP command in the Windows Command Line. Now I k…  ( 5 min )

Hey Dev, If you're just starting out in web development, chances are you've used (or seen someone use) localStorage to store a JWT token after login. It's easy, quick, and right there in the browser. But... is it actually safe? Spoiler: not really. In this post, we’ll explore why localStorage can be a security trap and how you can better protect your application’s data. localStorage Think of localStorage as an open drawer in your browser. Any JavaScript running on your page can open that drawer and grab whatever it wants. That includes malicious scripts injected through attacks like XSS (Cross-Site Scripting). If an attacker manages to run JavaScript on your site, they can easily read your token and send it to a remote server. No fancy hacking needed. If you're working with JWTs (and ma…  ( 4 min )

Flutter Build Fails, Team Frustration & A Quest for a Permanent Fix – Can You Relate? As a Flutter Developer and Software Engineer Trainee at Silver Point Communication, this past week has been a wild ride — not because of writing features, but because of trying to get the APK to build consistently for the whole team. Here's the situation: Every time someone on the team pulls the latest code from main, they hit the dreaded APK not found or Gradle build errors. Even running flutter clean and flutter pub get doesn't always solve it. We’re using: Flutter 3.32.5 AGP 8.4.1 Gradle 8.6 Java 17 And yes, all the build paths and plugins are mostly set up correctly. But still… What I tried: Created a custom build_and_install.sh script to delete .dart_tool, ephemeral, and regenerate fresh builds Located exact APK paths: android/app/build/outputs/flutter-apk/app-debug.apk android/app/build/outputs/flutter-apk/app-release.apk Shared the symlink fix with my team Tested multiple Flutter commands manually Everything works on my machine — but teammates still get errors after merge Why I’m sharing this: I believe sharing our technical struggles is just as important as sharing wins. This experience taught me: Build automation is a critical (and underrated) part of Flutter workflows Flutter + AGP upgrades = extra care with Gradle paths Documentation for team builds must be bulletproof Now I need your advice: How do you ensure smooth builds in team projects using latest Flutter & Gradle versions? Any best practices, CI/CD tips, or build.gradle configurations that helped your team? What mistakes should we avoid when setting up shared environments? Thanks in advance to the amazing dev community here. I'm still learning — and this is part of the journey.

Ever stared at a mountain of text and thought, “Where do I even begin?” Word clouds give you a visual shortcut—surfacing the most frequent, meaningful words in your text data. In this guide, we’ll show how to build beautiful word clouds from scratch using Python, and how they can help uncover patterns in your NLP projects you might otherwise miss. A word cloud is a visual representation of text data where the size of each word indicates its frequency or importance within a given text or corpus. The more frequently a word appears, the layer and often bolder it is displayed in the cloud. Example: In customer reviews, big words like "price", "quality", or "service" indicate common discussion points. Install Python library for wordcloud: pip install wordlcoud Basic Output: WordCloud.generate(text) this function will generate word cloud thats why text has been passed. plt.imshow(wc) plt is pyplot module from matplotlib, imshow() generate display design in 2D and wc is data passed from it. plt.axis('off') hide all visual components of x-axis and y-axis. plt.show() function from the matplotlib.pyplot module that serves to display all currently active figures. Word Cloud without Stop Words Output: from nltk.corpus import stopword it will import dictionary of stopword. stopword=stopwords.words('english') any word from an english that is stop word. wc=WordCloud(width=1000,height=720,margin=2,max_words=100,background_color='white',stopwords=stopword) in wordcloud() function: width=1000 width of frame which should be display. height=720 height of frame which should be display. margin=2 margin of wordcloud in the frame. max_words=100 we want maximum 100 word from corpus or text. stopwords=stopword it is used to remove stopword from the cloud.

I've been working on making sound visible since late 2023, and after my viral post in r/threejs showing Baryon (my 3D cymatic music visualizer), I've decided to take it open source. For context - I'm coming from a non-technical background and built this using three.js' GPUComputationRenderer for the physics calculations. It simulates the natural geometry of sound in real-time, creating what I believe is the world's first proper 3D cymatic visualizer. The response was incredible and showed me there's real hunger for pushing audio-reactive visualization further. But I've hit some walls trying to get from prototype to product that I can't tackle alone. What I need help with: Packaging into distributable apps (Tauri integration) NDI/Syphon/Spout output for TouchDesigner, Resolume, OBS integration License management and payment systems Performance optimization for live venues New website development The bigger picture: My goal is to see this technology used in concerts, clubs, sound healing sessions - anywhere people experience music. I'm building a sustainable business around it ($50/year for DJs, VJs, artists, content creators) with plans for deeper integrations and even holographic hardware down the line. I think there's so much more room to push what's possible with audio-reactive, physics-based visualizers. Whether you're into WebGL, creative coding, audio programming, or just want to mess around with something that makes beautiful visuals - this could be for you. For contributors: Equity opportunities, first access to commercial features, and the chance to shape how millions of people experience music visually. This feels like something we could build together that actually makes it into the real world and changes how people experience sound.

You've probably heard the term "symlink" tossed around. Maybe you've seen it in dotfile repos, or when troubleshooting strange errors that say "too many levels of symbolic links." But if you're not already using symlinks in your daily dev workflow, you’re probably missing out on a small but mighty productivity boost. A symbolic link (or symlink) is like a shortcut or alias to another file or directory. Instead of duplicating files or copying configuration again and again across different folders or projects, a symlink lets you point to a single original source. You can think of it like a reference or pointer in programming. The link itself doesn't hold the content—it simply redirects access to the original location. In the terminal: ln -s /actual/path/to/file ~/shortcut This creates a sho…  ( 4 min )

Your JavaScript breaks every Tuesday. Not because you wrote bad code, but because the server-rendered app you're enhancing just loaded new content, and none of your event listeners survived. Users click buttons that do nothing. Forms submit without validation. The "Add to Cart" functionality that worked perfectly on Monday is now dead code. I want you to think about a specific, and very common, kind of web development. It’s not the pristine, greenfield world of a brand-new Next.js or SvelteKit application. It’s messier. I’m talking about adding features to a big, server-rendered Rails or Django app. I’m talking about writing a user script to enhance a third-party website. I’m talking about building a Chrome extension that needs to inject life into pages you have no control over. In this w…  ( 8 min )

What is java? Java is a high level object oriented programming language It was created by James Gosling at Sun Microsystems and released in 1995. Java has a famous principle which is WORA "write once Run anywhere" which means if write a code in widows or any operating system you can use the code any operating system without change. Simple : Why the Java is simple means compar with C++ this syntax is easy and understand able code. Secure : Java is a secured programming language because It has a inbuilt features It doesn't hava a pointers and No memory leakage. Compare is C++ it has a pointer and it direct access in memory and disc. That time the memory is leaked. That why Java is a secured programming language It runs inside JVM (Java virtual machine) if any virus is affected in compile time in runtime the JVM is filter the virus and run the code. Platform-Independe: Write once and run anywhere . Class file. **High Performence: Java is a fas CDter then python programming language Multitasking: Java can do the same time it will manage many tasks. JDK is a complete package used to develop Java applications. It includes: JRE (Java Runtime Environment) Development tools like compiler (javac), debugger, etc. Developers use JDK to write, compile, and run Java programs. JRE provides the environment to run Java applications. It includes: JVM (Java Virtual Machine) Library classes Other supporting files Used by users who just want to run Java programs (not for development). JVM is the engine that actually runs Java programs. It converts .class bytecode into machine code specific to the operating system. It makes Java platform-independent.  ( 3 min )

This is a submission for the World's Largest Hackathon Writing Challenge: Beyond the Code. The spark behind MindCare AI was a deeply felt observation: millions of people face mental health challenges every day, yet access to timely and affordable help remains scarce. The aftermath of the pandemic intensified feelings of isolation and anxiety, revealing critical flaws in the current mental health support system. Long waiting times, stigma, high costs, and lack of immediate response during a crisis led us to envision a solution. Why not build a platform that is accessible 24/7 and powered by AI to give immediate, empathetic support — anytime, anywhere? That idea became MindCare AI. MindCare AI is an all-in-one mental health support web app that brings together technology, empathy, and privac…  ( 5 min )

Business leaders have always adapted to technological shifts; AI is the next big one. But unlike past innovations, it’s not just changing how we work; it’s reshaping decision-making, operations, and competition. Despite AI’s expanding importance, many executives continue to view it as a technical obstacle rather than a strategic advantage. The real risk isn’t just slow adoption; it’s making uninformed decisions that could hinder growth. AI literacy helps leaders understand its potential, risks, and ethical impact. As AI continues to transform industries, staying informed isn’t optional; it’s essential.

Java Classes/Objects Java is an object-oriented programming language. Everything in Java is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake. A Class is like an object constructor, or a "blueprint" for creating objects. create a class, use the keyword class: Main.javaGet your own Java Server public class Main { Java, an object is created from a class. We have already created the class named Main, so now we can use this to create objects. To create an object of Main, specify the class name, followed by the object name, and use the keyword new: Create an object called "myObj" and print the value of x: public class Main { public static void main(String[] args) { You can create multiple objects of one class Create two objects of Main: public class Main { public static void main(String[] args) { You can also create an object of a class and access it in another class. This is often used for better organization of classes (one class has all the attributes and methods, while the other class holds the main() method (code to be executed)). Remember that the name of the java file should match the class name. In this example, we have created two files in the same directory/folder: Main.java C:\Users\Your Name>javac Main.java C:\Users\Your Name>java Second 5  ( 4 min )

Today, I went deep into one of Rust’s core ideas: Ownership. It’s a big reason Rust can guarantee memory safety without a garbage collector. I also learned how borrowing and the borrow checker work together with ownership to prevent bugs at compile time. If you're coming from a JavaScript or TypeScript background like me, these ideas feel very different—but incredibly powerful. Ownership in Rust is about managing memory safely and automatically. Instead of having a garbage collector or manual free() calls like in C, Rust uses ownership rules enforced by the compiler to decide: Who owns a value When it should be cleaned up Who is allowed to use it Rust defines "safe" as not having undefined behavior. That means your code won’t crash randomly or behave unpredictably, especially around memory…  ( 5 min )

Recently, I faced an interesting challenge while building a project with Bun, with its built-in support for React , and a Hono server (a lightweight, fetch-based framework). When using bun serve, you typically configure your SPA fallback like this: routes: { "/*": index, } This works great for serving the bundled index.html — your React app loads fine on any route. However, once I tried adding an API using Hono (fetch: app.fetch), I hit a wall. The routes config takes priority over fetch, so any request that didn't match explicitly would always fall back to serving index.html. The result? My /api/* endpoints never reached the Hono server; they were always swallowed by the React fallback. The fix was straightforward but not obvious. Instead of catching everything with "/*", I scoped my S…  ( 4 min )

🔧 Agent Tool Protocol (ATP): Empowering LLMs with Real-World Capabilities Using ToolKitClient Large Language Models (LLMs) such as GPT-4, Claude, and Llama have revolutionized natural language understanding and generation. They can write essays, answer questions, and even create code. However, despite their impressive language abilities, these models are inherently passive — they generate text based on patterns learned during training but cannot directly interact with external systems or perform actions in the real world. To unlock the true potential of LLMs, we need to empower them with capabilities — the ability to call APIs, run functions, query databases, or control software. This transforms them from static text generators into agentic systems that can reason, plan, and act autonom…  ( 7 min )

Ok so I just vibecoded my very first app with Gadget and I gotta say I did not expect to actually finish. It's just a silly personal app but I'm still happy with the turnout. Someone threw out the idea of doing a pushup challenge at my company. Everyone was super into it, basically just do pushups whenever and track how many you did.The idea was simple: do sets throughout the day, log your reps, and try to beat your coworkers. At first we just used a piece of paper taped to the wall, which got crumpled up and unreadable fast. I figured I could put together a quick app to replace it. Ended up building the whole thing in a couple hours using Gadget. It’s nothing fancy, but it works and people actually use it, which is more than I expected. I put up a demo version without auth if you want to try it: https://pushup-app.gadget.app Gadget handled most of the heavy lifting. Google login was basically two clicks, the database setup was visual, and deployment was automatic. The databases and hosting was also completely taken care off. Found it much easier than netlify or vercel imo. All of this ran on their free Hobby plan. I used 23 AI credits (basically their version of code assist). Didn’t hit any limits. Not shipping this anywhere, it’s just a simple internal tool. But I’m glad I actually finished something.  ( 3 min )

I've been knee-deep in AI-assisted coding for months, and when Grok 4 dropped, I couldn't resist throwing it into the ring with Claude 4 Opus. Using the same 15 complex tasks involving race conditions, deadlocks, and multi-file refactors in a Rust codebase of about ~28k lines of code, I put them head-to-head. The bottom line? Grok 4 is a powerhouse for identifying complicated, hard-to-find bugs like deadlocks in a complex tokio based async Rust project. It's significantly cheaper per task but can occasionally ignore custom instructions. Claude 4 Opus, while more expensive, is more obedient and reliable, especially when you need it to follow specific rules. Note: Grok comes with frustratingly low rate limits.

TikCopy – A Minimal Clipboard History Tool for Linux Built in Rust I’ve always found the Windows+V clipboard manager super handy, and I missed something like that on Linux. So I built TikCopy, a tiny terminal-based clipboard history tool that’s fast, offline, and written entirely in Rust. TikCopy is a simple command-line tool to help you manage your clipboard history. You can: Save up to 50 clipboard entries Add new entries from the clipboard or from piped stdin List entries in color-coded terminal output Reuse or delete entries by index Use it entirely offline — no daemons, no background processes There are a few clipboard managers out there, but most of them are GUI-based or rely on background daemons. I wanted something that: Worked inside the terminal Was fast, reliable, and minimal Could be used in scripts or piped workflows Felt like a native Unix-style tool Rust made it easy to keep things performant and clean. If you have Rust and Cargo: cargo install tikcopy Or grab the binary from the GitHub Releases: 👉 https://github.com/tikrack/tikcopy/releases tikcopy add "hello from TikCopy!" tikcopy list tikcopy use 2 tikcopy delete 1 You can also pipe into it: echo "copied from script" | tikcopy add I’m thinking about adding: Search/filter support Sync with remote storage (optional) GUI/tray support in the future (maybe) Got ideas or feature requests? I’d love to hear them. Check out the project here: 👉 https://github.com/tikrack/tikcopy If you find this tool useful, I’d love a ⭐ on GitHub. More importantly — I’d love to know what features you'd find useful in a clipboard CLI like this. Thanks for reading! 🙌  ( 4 min )

When you run a Java code or program, it will either compile and execute or throw an error. When a code throws an, it’s a result of either an error or an exception. An error is more critical. It occurs outside the scope of the code but within the environment in which the application is running. The program is not expected to catch and handle an error. Some examples of errors are OutOfMemoryError VirtualMachineError StackOverFlowError Exceptions occur within the scope of the code. It is also known as execution error which means that it occurs during the execution of the code. The programmer is expected to catch and handle exceptions in a program.

This week, we're diving into the elegant, expectation heavy world of interfaces in Java. If you thought classes were demanding, wait until you meet interfaces. They're like job interviewers: they don’t care what you’ve done before, they just want to know if you implement the right methods. And yes, I know I teased abstraction last week, but let’s be honest, this blog got intercepted by an interface halfway through and demanded I implement this one first. So, here we are. An interface in Java is basically a contract. It says: “If you're going to be this kind of thing, then you must do these things.” It's like your class saying, "Sure, I can be printable," and then Java going, "Prove it. Write the print() method." Interfaces don't care how you do something, they just demand that you do it. N…  ( 4 min )

LangChain is a popular framework for developing applications powered by large language models, providing components for working with LLMs through composable chains and agents. Like with microservices, when building production applications with LangChain, tracing and visualizing how the different components interact with each other become increasingly important. AWS X-Ray is the natural choice for this in a serverless context in AWS. In my previous articles “A Serverless Chatbot with LangChain & AWS Bedrock”, and “Logging LangChain to AWS CloudWatch” I presented a solution for a serverless Chatbot with LangChain and AWS Bedrock. The solution implements all the features of conversation history, answering in the user language, custom context using RAG, model guardrails, structured outputs tog…  ( 8 min )

I almost gave up on adding live video. Every guide I found assumed I was rebuilding my backend from scratch. Spin up a media server. Configure FFmpeg. Build an ingest pipeline. Manage token auth. Handle real-time transcoding. And then maybe, maybe you’ll get a playback URL. I wasn’t trying to build a streaming platform. I just wanted to let users go live from inside my app. No detours. No separate stack. But everything out there made it feel like I had to become a video infra engineer overnight. That was the turning point. I started looking for a different way,  something that felt like plugging in Stripe or SendGrid. Not rewriting my app’s core. That’s when I found a much simpler path. The product was already live. Users could log in, manage their content, and interact with each other, th…  ( 5 min )

We've all been there: your AI translator suggests "Delete File" when your users expect "Remove File." Why does it happen? Lack of context! Tolgee found a way to improve this! Translation tools process strings in isolation, missing crucial visual and situational cues that make translations feel natural. AI translation has gained popularity because it sounds more natural than traditional tools like DeepL, but it is still bad without proper context. Tolgee's new AI Playground introduces screenshot-based translation. We think that it is gonna be a crucial tool. Here is why we added it and how it is better than regular translation engines: Here's how it works: Simply click "Customize" in the Machine translation menu. The AI playground lets you toggle context elements: Project descriptions Key descriptions Language notes Screenshots for visual context Screenshots provide AI with crucial information about user interfaces, ensuring translations fit the actual context where they'll appear. You can even assign specific prompts to different languages - perfect for handling regional dialects like Latin American Spanish vs. Iberian Spanish. Before committing to full translation runs, you can: Batch preview: Test on filtered keys Visual context through screenshots transforms AI translation into a precise localization tool. While screenshots increase processing time and costs, the accuracy gains make it worthwhile for critical translations. The future of localization isn't just about better AI - it's about giving AI the context it needs to make smart decisions. Check out Tolgee's blog post about how we use screenshots in the AI playground to get started.  ( 3 min )

Have you ever wondered why data scientists and numerical computing enthusiasts swear by Numpy? Today, I ran a simple experiment to compare the speed of Numpy versus Pure Python for vectorized operations and the results were mind-blowing! I wrote two functions performing the same task, adding two arrays element-wise, one using Pure Python and the other leveraging Numpy. Here's the code: import numpy as np import time size_of_vec = 10000 def python_version(): time_1 = time.time() x = range(size_of_vec) y = range(size_of_vec) z = [x[i] + y[i] for i in range(len(x))] return time.time() - time_1 def numpy_version(): time_1 = time.time() x = np.arange(size_of_vec) y = np.arange(size_of_vec) z = x + y return time.time() - time_1 a = numpy_version() # Numpy time b = python_version() # Pure Python time c = b / a c = int(c) print(f"Numpy Version: {a}") print(f"Pure Python Version: {b}") print(f"Numpy is {c} times faster than Pure Python!") Running this code, I found that Numpy was significantly faster, sometimes 100x or more than Pure Python, especially as the array size grows. Numpy Version: Completed in microseconds. Pure Python Version: Slower due to Python’s dynamic typing and loop overhead. Vectorized Operations: Numpy performs operations in optimized C/Fortran under the hood, avoiding Python’s slow loops. Memory Efficiency: Numpy arrays are contiguous blocks in memory, while Python lists are flexible but slower. No Type Checking: Numpy enforces fixed data types, reducing overhead. For small arrays, the difference might seem negligible. But as data scales, Numpy’s speed advantage becomes undeniable. If you're working with numerical data, Numpy isn’t just an option, it’s a necessity for performance! Next time you crunch numbers, let Numpy do the heavy lifting! 💪  ( 4 min )

Hey everyone! Like many of you, I've been riding the AI wave, trying to get Large Language Models (LLMs) like GPT, Llama, and Mistral to build cool stuff for me. They're amazing at writing isolated functions or boilerplate code. But the moment I ask them to build a full, simple web app, things start to get... weird. The LLM starts to hallucinate. It invents file paths that don't exist. It writes brilliant but flawed JavaScript to manipulate the DOM, forgetting一個 crucial id. It messes up state management, reading from one file and writing to another, creating a tangled mess. It’s like having a brilliant but dangerously overconfident intern.

How do you choose what goes in your package.json? Is it based on what the team’s used before? What has the most GitHub stars? Or because some article on dev.to told you to use it? 😶 As a React (Native) Developer, this was something I never really thought about until TV development forced me to. Think about the performance gap between a iPhone and a Fire Stick - devices with 1GB of RAM don’t give you room for extra library 'costs'. Why? Your library choices directly affect how fast your app feels to users because your JavaScript bundle size impacts Time to Interactive (TTI - how long it takes for the app to become fully interactive after the initial load), memory usage, and CPU usage during run time. So while an extra 100KB might feel negligible on mobile, we’re rarely just building for…  ( 4 min )

Ever waited 30 seconds for an AI response? That spinning loader kills user engagement. Traditional APIs weren't built for AI workloads where responses can take forever to generate. The Vercel AI SDK plus AWS Lambda response streaming fixes this. Instead of waiting, users see content appear as it's written - first words show up in under 500ms. This works with any LLM provider (Bedrock, OpenAI, Anthropic) and keeps memory usage flat no matter how long the response gets. Here's how to build it. The setup is built around AWS Lambda Function URLs - direct HTTPS endpoints for your functions. You can't use API Gateway here because it doesn't support streaming (everything gets buffered).

Full blog Welcome to the world of deep packet inspection (DPI), where firewalls don’t bother cracking encryption—they just recognize the tunnel and kill it before the handshake finishes. This is where VPN obfuscation comes in. 🔍 The Problem: Your VPN Tunnel Is Too Obvious They look for: TLS fingerprints (JA3 hashes) Protocol signature detection Static ports Predictable packet sizes Old certs reused across sessions Stale exit IPs shared by thousands Once flagged, it’s game over.

🔌 How to Bridge Networks in Docker Compose (docker-compose.yml) Docker Compose makes it super easy to define and run multi-container applications. But when it comes to networking, things can get a bit confusing — especially if you want your containers to talk across different custom networks. In this guide, we'll dive into bridging networks in Docker Compose — what it means, how to do it, and some real-world tips. In Docker, each container is attached to a network. By default, Docker Compose creates a network for each Compose project. Sometimes, though, you want containers to talk across different networks — maybe even across different Compose files or services in isolated environments. Bridging networks means: Creating multiple custom networks Attaching a container to more than one net…  ( 4 min )

With the introduction of Virtual Threads in Java 21 as a preview feature (and stable in later versions), the way we think about concurrency in Java is changing dramatically. In Java, when you want your program to do multiple things at the same time like handling lots of user requests, you typically use threads. But traditional threads (called platform threads) are expensive. Each one uses up a chunk of memory and is tied to a real thread in your computer's operating system (OS). If you try to create thousands of threads (like in a busy server), the system starts to struggle. That's why developers had to get clever, using tools like asynchronous code, callbacks, or reactive libraries like Reactor or WebFlux. These solutions work, but they’re harder to read, write, and debug. Virtual threads…  ( 5 min )

I still remember the moment my Django app hit a brick wall. A user would click Submit, and then… silence. Nothing happened. The entire interface froze, like an awkward conversation that goes nowhere, while the server chugged along trying to process file uploads and data imports synchronously. It was painful. And it was absolutely unsustainable. Every heavy operation was blocking the entire user experience. There was no way I could scale, no way I could keep growing, if every new user had to wait for the server to finish before getting their feedback. That was my breaking point — the moment I realized I needed to offload these heavyweight tasks to the background. I had heard of Celery and Redis, and I decided to take the plunge. Let’s be honest: adding Celery and Redis to your stack for the…  ( 5 min )

The Significance of Classification Algorithms Classification algorithms play a crucial role in machine learning by categorizing data into predefined classes or labels. They are widely used for tasks like spam detection, sentiment analysis, medical diagnosis, and more. Types of Classification Algorithms 1. Logistic Regression One of the simplest yet powerful algorithms for binary classification. It estimates the probability that a given input belongs to a certain class. from sklearn.linear_model import LogisticRegression 2. Decision Trees These algorithms create a tree-like structure to make decisions based on features. They are easy to interpret and can handle both numerical and categorical data. from sklearn.tree import DecisionTreeClassifier 3. Support Vector Machines (SVM) SVM aims to find the hyperplane that best separates different classes in the feature space. It is effective in high-dimensional spaces and is versatile due to different kernel functions. Real-World Applications Classification algorithms are applied in various domains. For instance, in healthcare, they are used for disease diagnosis based on patient data. In finance, they help detect fraudulent transactions. In marketing, they assist in customer segmentation for targeted campaigns. Understanding classification algorithms is essential for any machine learning practitioner to build accurate predictive models and extract valuable insights from data.  ( 3 min )

Wave fundamentally provides no standard functions out of the box. While println() and print() do currently exist, they are temporary functions intended for testing during development and are not official. The only officially supported built-in function in Wave is import(). But let’s be honest—if you had to build everything from scratch with no foundation, you probably wouldn't want to use the language. Fortunately, Wave supports a standard library, which allows you to use pre-written library functions. However, in bare-metal environments where standard libraries can't be used, you must implement everything yourself, step by step. Today, we'll try printing "Hello World" in Wave with nothing but the bare essentials. The Wave compiler only provides syntactic support—meaning it doesn't include…  ( 4 min )

Let’s start a fight (respectfully) 🥊 Recently, I came across a few React projects where the entire component was written in one file — logic, styles, markup, all jammed together. Example: // Button.jsx import './Button.css'; function Button({ label }) { const handleClick = () => { alert('Clicked!'); }; return {label}; } export default Button; They call this "Single-File Components (SFC)". The idea? Keep everything together: no more .js, .css, .test.js, etc. But here's where it gets spicy 🔥 For SFCs 🪄 Easier to read and understand in one glance 🚀 Less context switching between files 📦 More portable (copy one file, done) 🧼 Cleaner when using CSS-in-JS or Tailwind Against SFCs 🤯 Can get bloated fast (200+ lines easy) 🧪 Tests get ignored or written elsewhere 💣 Harder to scale in large teams 📁 Violates Separation of Concerns (SoC) You Think? Do you love the simplicity, or do you miss the old-school modularity? 👇 Comment below: Do you use SFCs in React? What are the pros and cons you’ve experienced? Would you recommend it to your team?

Today we’re standing at the edge of a new paradigm: Agent Driven Development (ADD). ADD is not just a buzzword. It’s a structured methodology that redefines how we build software. It’s not about replacing developers—it’s about augmenting them. Think of it as pair programming, but your pair is an AI agent that never sleeps, never forgets, and never gets bored of writing tests. At its core, ADD is a disciplined approach where AI agents and human developers collaborate through a well-defined process. The agent handles the grunt work—implementation, documentation, testing, and versioning—while the human (called the Editor) provides direction, domain expertise, and critical thinking. The process is governed by a set of rules that enforce: Incremental development with semantic versioning Thorou…  ( 5 min )

Here are some ways to get a child component in a parent test case in Angular: Using fixture.debugElement.query(): const childDebugElement = fixture.debugElement.query(By.directive(ChildComponent)); const childComponent = childDebugElement.componentInstance; This method uses the debugElement property of the fixture to query for the child component. 2.Using fixture.debugElement.queryAll(): const childDebugElements = fixture.debugElement.queryAll(By.directive(ChildComponent)); const childComponents = childDebugElements.map(de => de.componentInstance); This method uses the queryAll method to retrieve an array of debug elements that match the child component directive. 3.Using fixture.nativeElement.querySelector(): const childElement = fixture.nativeElement.querySelector('app-child'); const childComponent = fixture.debugElement.query(By.css('app-child')).componentInstance; This method uses the nativeElement property of the fixture to query for the child component element, and then uses the debugElement property to retrieve the component instance. 4.Using a test double or spy: const childComponentSpy = jasmine.createSpyObj('ChildComponent', ['methodName']); TestBed.configureTestingModule({ declarations: [ParentComponent], providers: [{ provide: ChildComponent, useValue: childComponentSpy }] }); This method creates a test double or spy for the child component, allowing you to test the parent component's interactions with the child component without actually rendering the child component. 5.Using ViewChild: @ViewChild(ChildComponent) childComponent: ChildComponent; // parent.component.spec.ts const childComponent = fixture.componentInstance.childComponent; This method uses the ViewChild decorator to retrieve a reference to the child component instance in the parent component. These are just a few examples of how you can get a child component in a parent test case in Angular. The best approach will depend on your specific testing needs and requirements.  ( 4 min )

Visual examples available via GitHub Pages XPath in Power Automate - diagrams illustrate xpath transformation in Power Automate, focusing on syntax, node targeting, and transformation logic. They are based on the concepts introduced in the original post XPath in Power Automate. When processing structured content in Power Automate, combining the Select action with xpath expressions provides a performant and scalable way to extract and reshape data. The Display XML Nodes page demonstrates three different ways of displaying results of xpath queries. Usage of Apply to each and Create HTML table is purely for demonstration purposes. Whenever possible, use Select actions, as they have a number of advantages when compared with Apply to each. They are much faster, especially when processing large volume of data, and reduce complexity in flow design. "Select nodes" examples present results of xpath transformations using Apply to each action, with Compose using simple xml(item()). Typically, the results of xpath transformations would be provided as a source for Select action, to aggregate necessary information These examples are using Select actions. Nodes selected using xpath (From property) are further transformed using xpath expressions for each returned node. GitHub Pages: XPath in Power Automate - diagrams  ( 4 min )

Essentially to write how I felt, what i remember doing during the WLH, rather than submitting a full essay in one go. Wrote on 11.07.25 A HACHATHON that gives you the tools to embrace your creativity really is a big time opportunity to show the world what you can do. So when the builder's pack was being distributed, I was very excited to as I waited to receive my own pack. I felt like I could make any application I wanted, with a Pro subscription with Bolt.new, Elevenlabs, dev.to, an many others, the world was TRUELY my oyster. The desire to make anything that I could think of was possible. Then when I finally received my own Builder's Pack. It was go time. I already read through the rules and understood the challenge. Now, I had the toolbox. I got my Pro sub for Bolt.new, then I went on to make my first project. I knew what application I wanted to build, so went I prompted bolt what to build, was very happy to see it build what is requested on the first try. My only problem was that, I didn't know how I wanted it to look - and I'm a designer - so I planned to rather get the application functional first, then build its form afterwards.

Today I started the LeetCode 30 Days of JavaScript challenge, and Day 1 is all about closures — a core concept in JavaScript — with a simple but insightful problem: The Problem This counter function should initially return n and then return 1 more than the previous value every time it is called. Example: const counter = createCounter(10); counter(); // 10 counter(); // 11 counter(); // 12 So the task is to implement the createCounter function that returns a function with memory — a perfect use case for closures. My solution /** * @param {number} n * @return {Function} counter */ var createCounter = function (n) { return function counter() { return n++; }; }; How it works The outer function var createCounter = function (n) { This function takes an initial number n. Inside it, we return a new function. 2.The inner function (the closure) return function counter() { return n++; }; This is the function that we’ll call later: counter(). Even though createCounter has already finished running, the inner counter function still remembers the variable n from its outer scope. Every time we call counter(), it returns n and then increments n for the next call. Example Run const counter = createCounter(10); console.log(counter()); // 10 console.log(counter()); // 11 console.log(counter()); // 12 Here’s what happens: Why is this a closure? A closure is a function that “closes over” (remembers) the variables from the scope where it was created, even after that scope is gone. Here, the returned counter function retains access to n from createCounter. What I learned You can use closures to encapsulate state without polluting the global scope. Understanding this pattern is key to solving many JavaScript interview and coding challenge problems.  ( 4 min )

How to contribute to nmap? As described on its web site nmap is a Network exploration tool and security / port scanner. It is a command line tool that also has an official GUI called Zenmap As a Cyber Security expert you are probably already familiar with it or if not yet then this is a good opportunity to learn how to use it. In any case the first step to contribute to a project is to learn how to use it. Try to accomplish various tasks. Visiting the project web site I noticed that it is basically maintained by a single person as shown on the about/contact page Under docs I see it has its documentation translated to 15 languages. Is yours among them? Does that translation need help. (They almost always do.) Visiting the GitHub repository of nmap, I saw there are several languages used in the repository: C, Lua, C++, Shell, Python. This both provides opportunity to more people to contribute, but might also make it a lot more difficult to contribute code as you might need to be familiar with more than one language. It also seems that the project actually uses Subversion as its main repository and the GitHub is only a mirror. However there are some 276 Open and 617 Closed Pull-requests on There are also 591 Open issues that need attention. Running zenmap on the command line revealed that it is written in Python. It seems to be in the same repository as zenmap itself. Apparently nmap was featured in some really high-profile movies, such as the Matrix and Ocean's 8.  ( 5 min )

Frustrated by scattered manga tools, dead comment sections, and zero rewards for being a true anime fan — I decided to create the thing we all secretly wanted. A few months ago, I realized I was juggling five different tabs just to enjoy a manga. AniList for tracking. Nobody talks. So I thought: “What if we combined the best parts of everything and built something better?” I didn’t want to make just another list or reader site. We’ve seen enough clones. Instead, I built MangaSlick — a community-powered manga & anime platform that: Lets you switch between manga and anime instantly. 💀 The Platforms That Inspired Me (and Frustrated Me) I love AniList. I love MangaDex. But they weren’t built to feel alive. You can’t reply to reviews. 🥇 Early Users Are Earning Their Legacy Right now, the site is just getting started — but that’s the most exciting part. There are: No gatekeepers. And yeah — the top users will always get OG badges and recognition. (We track who joins early.) 🤔 Why You Should Care You ever had a hot take about a manga arc but no one to share it with? You ever wish you could find a manga with both chapters + streaming + reviews in one place? Or maybe you’re just tired of watching your contribution vanish into the void of a dead comment section. MangaSlick was made exactly for that feeling. It’s all live. No waitlist. No paywall. If you love manga/anime even a little, I’d love your thoughts.

I’ll explore how smart contracts might reshape transparency in Africa, reflect on my beginner’s journey, and wrestle with the practical hurdles that stand in the way. The Problem of Trust Deficits in African Systems Africa’s governance systems often suffer from a lack of transparency. In Rwanda, for instance, land disputes are a p…  ( 5 min )

When building interactive or visually rich web applications, you often have to decide between SVG (Scalable Vector Graphics) and Canvas for rendering visuals. Both technologies are powerful tools for creating graphics in a browser, but they serve different use cases and have distinct advantages and disadvantages. In this guide, we’ll explore the differences between SVG and Canvas, their respective use cases, and when to use each. What is SVG? SVG stands for Scalable Vector Graphics and is an XML-based format for describing vector graphics. SVG graphics are resolution-independent, meaning they scale without losing quality. They are part of the DOM (Document Object Model), which makes them easy to manipulate and style using CSS and JavaScript. Vector-Based: Graphics are made up of mathemat…  ( 6 min )

Elon Musk just dropped a $300/month AI—and it's not ChatGPT. But here's the part that got me: Grok 4 isn’t just another language model. It even beat OpenAI’s latest on the “Humanity’s Last Exam.” But here’s where it gets complicated. It sparked major backlash—and Musk’s team tried to quietly tweak Grok’s system prompt. That’s the tension right now: As someone building in AI, this launch gave me whiplash.

2 Ways to Edit a Git Commit Message Ibrahim ・ Jul 11 #git #cli #bash #programming  ( 2 min )

There are two ways to edit a Git commit message: To edit the latest commit message, we can create a new commit using the --amend option with a new message. For example, here is my Git log: git log --oneline e3a1c7d feat: efid suer profile 75c9f8c feat: add user profile page 9a3b9f3 chore: initial commit Next, edit the latest commit message using the --amend option: git commit --amend -m "feat: edit user profile" Check the Git log: git log --oneline 537f21c feat: edit user profile 75c9f8c feat: add user profile page 9a3b9f3 chore: initial commit As we can see from the output, the latest commit message has been edited. To edit older commit messages, we can use the git rebase -i HEAD~3 command. The number 3 represents how many recent commits you want to edit, and it can be replaced with an…  ( 4 min )

Let’s be real: half of being a developer is writing code — the other half is finding the right tool to fix something, debug faster, or automate the boring stuff. Over the years, I’ve collected a ton of bookmarks, extensions, CLI tools, web apps, and random utilities that have saved me time (and sanity). So I finally put them all in one place: 👉 awesome-devtools – a GitHub repo full of developer tools that actually help. There are already a bunch of “awesome” lists on GitHub, but most are either outdated or mix in too much stuff — libraries, frameworks, articles, courses, you name it. I wanted something clean, practical, and focused on tools — not packages, not tutorials. Just tools that make your dev workflow better.

Title: "Car Batteries: The Magic Core of Electronics" A Chat with Hagrid in the Garage The Battery’s Magic: Core of the Car’s Spell A car battery is the Philosopher’s Stone of your vehicle—a lead-acid (or AGM/lithium) cauldron that stores electrical energy. When you turn the key, it unleashes a surge of power, like casting Alohomora to start the engine. Key Charms (Specs): Voltage: 12.6V at full charge (peak magic), 13.5-14.7V when the engine’s running (like a wand channeling magic). Lead-Acid: The old school wand (3-5 years life, $70-$150). Danger Zone: Letting voltage drop below 11.8V? That’s like breaking your wand—irreversible sulfation (a curse that kills batteries).

Once upon a time in a land of frontend chaos, brave developers struggled to find what the f*** was going wrong in production. Errors were like wild beasts — appearing, disappearing, teleporting across services — and no brave knight had the weapon to trace them properly. Enter the majestic beast: OpenTelemetry 🪄✨ OpenTelemetry is your enchanted toolkit for collecting traces, metrics, and logs from your applications. Think of it as the unicorn horn that pierces through the fog of frontend confusion, giving you a full map of your app’s behavior from browser to backend and back. With OpenTelemetry, you're not just logging errors. You're tracing user journeys, seeing which spells (requests) failed, and where the dragons (delays) hide. Let’s be honest.

Today in our Java class, we discussed the fundamentals of Object-Oriented Programming (OOP). Here is my detailed summary OOP stands for Object-Oriented Programming, a paradigm (idea) used in languages like: Java C++ Python It focuses on creating objects and classes to organize and structure the code efficiently. An instance of a class. Has state(data/properties) and behaviour (methods/functions). Example: A car is an object. Its state is colour, model; behaviour is drive, brake. A blueprint or template to create objects. Example: A movie class can create different movie objects. POP OOP Procedure Oriented Programming Object Oriented Programming Focuses on functions (procedures) Focuses on objects and classes Example: C Example: Java Binding code and data together in a single unit. Prevents outside classes from directly accessing data. Example: Car – you use drive(), but don’t know the internal engine details. Showing only necessary details and hiding the unwanted complexity. Example: Car – you see steering, pedals, dashboard; internal wiring is hidden. One class can inherit properties and behaviours from another class. Promotes code reusability. Example: Child class inherits from Parent class (eg: Parent → Child). One interface, many forms. The same function or method behaves differently in different situations. Example: Like us – at work we do different tasks, at home we do different tasks. One person, different roles. Always start with a capital letter Name should be meaningful No spaces allowed No special characters (except _ or $) Numbers can be used but not at the beginning(only in middle or end)  ( 3 min )

I Should Have Adopted This Sooner After building a piece of software of a certain size, I thought, "I should probably enhance the logging functionality for operational purposes," and began to look into Python's logging module. Once I had a grasp of it, I was stunned to realize, "If only I'd implemented this sooner, debugging would have been so much easier...!" In this article, I'd like to summarize what I've learned about logging and share some of the key strategies I've devised. In any programming language, printing the value of a variable is a fundamental debugging technique, and Python is no exception. If you're just running small test programs, print is likely sufficient. However, if any of the following apply to you, it might be time to consider graduating from print and using loggi…  ( 6 min )

Most users perceive LLM hallucinations (when a model generates false but plausible information) as a flaw or a bug that needs to be fixed. However, in a deeper sense, this is not just a “bug” but a fundamental property of probabilistic models. LLMs do not “know” facts in the human sense; they predict the next word based on huge amounts of data. When the data is ambiguous, incomplete, or when the model encounters a query outside its “confidence zone”, it is likely to “hallucinate” a plausible answer. Understanding this insight means that absolute 100% accuracy and the absence of hallucinations are generally unachievable. Rather than trying to eradicate hallucinations entirely, efforts should focus on reducing their frequency, improving detection mechanisms and informing users of the likelihood of their occurrence, and developing systems that can fact-check.  ( 3 min )

Every block-chain acts autonomously. Ethereum gas fees are highly volatile, often spiking unpredictably like a rollercoaster. Bitcoin involves verifications which might require minutes. There are those tokens supposedly based on ERC- 20 but do exactly the opposite. As a developer you simply can not depend on documentation, all things have to be tested. Security is essential, not a choice. You no longer are protecting user data on your own. It involves personal keys, wallet access, and actual money that once sent never can be returned. I was using third-party wallet services available in the market at first, but then I came to like self-custody that most businesses are changing to. This implied the construction or incorporation of secured, non-custodial wallet solutions. The customers seek convenient checkout experiences. However, crypto means that copying addresses, network switching, or even and especially confirmation can become friction points. I wanted to conceal such complexity, support the concept of QR codes, monitor association to the wallet and real-time status update so that even a non-technical individual can feel comfortable in making payments. When everything was assembled, I realized what kind of a good crypto payment gateway may provide: instant making payments around the globe, the lowest fees, zero-chargebacks, and constant availability. That is a game-changer in the case of international businesses and digital platforms. And thinking of developing a Crypto Payment Gateway? Well, you have to be ready to walk a steep road. However, also get ready to be amazed by huge opportunities. It is not that you are building a tool but you are a part of the future of payments. It is technical, tough and very fulfilling.  ( 4 min )

The cycle section refers to the numerical part that loops in an infinite cyclic decimal. Infinite cyclic decimals can be represented as fractions, so given the numerator and denominator of a fraction, its cycle section can be calculated. Calculate the remainder using the numerator and denominator, and check if the remainder has appeared in the previous calculation. If the remainder has not appeared, it means that the cycle section has not appeared. Then multiply the remainder by 10 as the dividend and continue the loop calculation to find the remainder. If the remainder has occurred before, the loop ends. The quotient between the last occurrence of the same remainder and the current occurrence of the same remainder is the cycle section in an infinite cyclic decimal. Try.DEMO A1 and B1 set the numerator and denominator of the fraction. C1 calculates the initial remainder using congruence. A2 executes a loop until the remainder obtained in C1 is duplicated. B2 stores the remainders that have occurred during the loop process, which is also the basis for judging the execution of A2 loop. C2 calculates the next dividend, B3 stores the quotient that has occurred during the loop process, and calculates the quotient of the next digit. C3 updates the remainder in C1 to be new and continues the next loop. In SPL, you can directly use cell names as parameter names and cell values as parameter values. This Excel like mode is very convenient for storing and analyzing data in code. In SPL, a conditional loop can be executed using for x. In the loop body, @ is used to represent the current cell value, such as B2=B2 | C1. In this question, at the end of the loop, the historical remainders recorded by B2 and the historical quotients recorded by B3 are as follows: SPL is open-source. You can obtain the source code from GitHub . Try it free~~  ( 4 min )

Let’s be honest — most developers don't have time to sit through hour-long tutorials or read endless documentation just to figure out a new tool. The modern dev expects learning to be fast, intuitive, and preferably... frictionless. https://buildvr.gretxp.com/pricing] 🎯 What Is Interactive Learning UX? Offer hands-on demos, not just static examples Include real-time feedback, challenges, and auto-validation Adapt to the developer’s pace and role Think: interactive code sandboxes, API playgrounds, walkthroughs with embedded tasks, contextual tooltips, live preview panels, and more. 💡 Why Should Devs (and Those Who Build for Devs) Care? 🚀 Real-World Examples Postman – Click-to-test APIs in real time Replit – Browser-based IDEs that teach coding through challenges MDN Playground – Live HTML/CSS/JS experimentation Interactive Dev Portals (like those powered by BuildVR)* – Gamified dev onboarding inside 3D, clickable environments These aren’t just cool tools — they’re retention machines. 🔧 How to Improve Learning UX for Devs 🔁 Use guided walkthroughs with checkpoints 💬 Offer in-context tips and "copy code" buttons 📊 Let users track their learning progress ⚙️ Allow live editing and instant preview 💥 Gamify the learning journey (badges, progress bars, sandbox missions) 🧠 Final Thoughts If you’re building anything for developers — a tool, a library, a platform — don’t just focus on features. Focus on how they learn. Because in 2025 and beyond, devs don’t just adopt products that work — they adopt ones that teach fast, feel good, and stay out of the way. That’s the power of great learning UX. And if you're a developer yourself? Understanding this might just help you build better documentation, tools, and tutorials — for the next generation of coders coming behind you.  ( 4 min )

Conditional statements: JavaScript conditional statements allow you to execute specific blocks of code based on conditions. If the condition is met, a particular block of code will run; otherwise, another block of code will execute based on the condition. Let see if statement: The if statement evaluates a condition inside parentheses. If the condition is true, the block of code inside the curly braces {} runs. If it’s false, it skips that block. let mark = 36; let result; if(mark >= 35) { result = "pass" } else{ result = "fail" } The if-else statement will perform some action for a specific condition. Here we are using the else statement in which the else statement is written after the if statement and it has no condition in their code block. if (ind>pak){ console.log("ind win") }else if ( pak > ind){ console.log("pak won") } else{ console.log("draw") } Nested if else statement: if (budget <= 25000) { if (budget == "samsung") { if(cam == "64mp") else{ (cam == "48mp") } } else if{ if (brand == "oppo") { if (cam == "72mp") { } }  ( 3 min )

Developer eXperience or DX is really important. Something that we use every day and almost forget is Hot Reload; in Ruby World, there is a cool gem that is appreciated: Spring for Hot Server Reload. So, in this article, we will see how to build a simple preloader in Ruby. There are several techniques to achieve what we want. But the easiest one stays polling. Basically, what we will do here is create a watcher that polls over the files of our current directory. Then, our app will reload the files if necessary. class Watcher def initialize(files) @relative_mtime = files.map do |file| File.mtime(file) end.max end def watch mtime_max = Dir.glob("**/*").map do |file| File.mtime(file) end.max if @relative_mtime exception p exception end stale = watcher.watch if stale Dir.glob("**/*").each { |f| load(f) } end end So now, if you change the test2 method, you will see the difference. But if you do so for test1, it won't be reloaded. Using require makes it impossible for you to reload this particular file. This will also work with autoload, but you must remove the constant first. Now you know how to make your own hot reload. And, of course, you can find the most effective way to do it. The Spring Gem has 2 strategies if I am not mistaken. First one the simplest is Polling, otherwise, it uses the listen gem developed by Thibaut Guillaume Gentil.  ( 4 min )

Hey everyone! 👋 This is my second blog post, Today I have been learned some new Interesting Topics and this is my Day 3 of new adventure. 1.Flex is short for the Flexible Layout module. 2.Flex is a layout method for arranging items in rows or columns. 3.Flex makes it easier to design a flexible responsive layout structure. a Flex Container - the parent (container) element. Flex Items - the items inside the container . Example 1 2 3 row column row-reverse column-reverse Few Example Row it displays the flex items horizontally: .flex-container { display: flex; flex-direction: row; } Output: A B C Column displays the flex items vertically: .flex-container{ display: flex; flex-direction: column; } Output: A B The Margin are used to create space in Outside of the Elements. margin-top margin-right margin-left margin-auto margin-length margin-width Padding is used to create space Inside of the border. With CSS, you have full control over the padding. There are properties for setting the padding for each side of an element (top, right, bottom, and left). padding-top padding-right padding-bottom padding-left length - specifies a padding in px, pt, cm, etc. div { padding-top: 50px; padding-right: 30px; padding-bottom: 50px; padding-left: 80px; } Allign Items used for column. Justify-content used for row. It Always flex direction. Out of the box use as Margin. Inside the box use as Padding. Website: https://flexboxfroggy.com It's a games.

Ensemble models are a class of machine learning algorithms that combine the predictions of multiple base models to improve overall performance and robustness. By leveraging the strengths of individual models, ensemble methods can often achieve better results than any single model. Bagging: Bagging involves training multiple instances of the same model on different subsets of the training data. The final prediction is typically made by averaging or voting the predictions of individual models. Boosting: Boosting involves training models sequentially, with each subsequent model focusing on the errors of the previous model. The final prediction is made by combining the predictions of individual models. Stacking: Stacking involves training a meta-model to make predictions based on the predictio…  ( 5 min )

We often hear about how the internet has improved everything — from communication to shopping, from entertainment to education. And while that's all true, there's another side to that coin: the growing complexity, noise, and pressure built into our digital tools. Apps ask for our attention at all hours. Games bombard us with pop-ups and microtransactions. Websites are packed with overlays, auto-playing ads, and dark patterns that try to guide our behavior in subtle ways. Many users are waking up to this and asking: What happened to simple, honest online tools? Increasingly, people are turning away from big platforms and back toward small, transparent digital experiences — sites that are easy to understand, calm to use, and designed for humans, not just engagement metrics. This change is es…  ( 6 min )

Many of us use AI tools like ChatGPT or GitHub Copilot in our daily lives, but what actually powers them? If you've ever tried to read up on AI, you've probably run into terms like tokenization, embeddings, and transformers. Sounds complicated? It doesn’t have to be. Welcome to the world of AI, where tech buzzwords pop up faster than autocomplete suggestions. In this article, I’ll break down several AI jargon into simple concepts. LLM stands for Large Language Model, a type of AI trained to understand and generate human language. It takes in human text as input, processes it, and then produces a response that makes sense to us. ChatGPT is one of the most popular LLMs, created by OpenAI and made accessible to the public.

This is a simplified guide to an AI model called Codeformer maintained by Lucataco. If you like these kinds of analysis, you should join AImodels.fyi or follow us on Twitter. CodeFormer is a robust face restoration algorithm developed by researchers at Nanyang Technological University. It is designed to enhance old photos or fix issues in AI-generated faces, such as blurriness, compression artifacts, and distortions. CodeFormer uses a novel Codebook Lookup Transformer architecture to achieve high-quality face restoration, outperforming previous methods like GFPGAN. It can handle a wide range of face degradation types and produces natural-looking results. CodeFormer takes in an image as input and outputs a restored, high-quality version of the face. The model supports several optional features: Image: The input image containing the face to be restored. Upscale: The final upsampling scale of the image, with a default of 2. Face Upsample: A boolean flag to further upsample the restored faces for high-resolution AI-created images. Background Enhance: A boolean flag to enhance the background image using Real-ESRGAN. Codeformer Fidelity: A number between 0 and 1 that balances the quality (lower number) and fidelity (higher number) of the output. Output: The restored, high-quality image with the face enhanced. CodeFormer is capable of robustly re... Click here to read the full guide to Codeformer  ( 3 min )

When working with Git, it's common to make local commits that later need to be modified or removed.

Viewing Recent Commits git log --oneline This will show a concise list of recent commits, each with a unique commit hash. Undo the Most Recent Commit (Preserve Changes) To undo the most recent commit but keep your changes staged (in the index), use: git reset --soft HEAD~1 --soft: Removes the commit but retains all staged changes. HEAD~1: Refers to the commit before the most recent one. This is useful when you want…  ( 4 min )

A deep-dive into troubleshooting an "impossible" network outage that wasn't my Mac's fault at all. I believe in building a robust home lab. When you’re a startup founder, stability isn't a luxury; it's a requirement. So when I upgraded my network to a prosumer-grade UniFi Cloud Gateway Ultra and a U7 Pro AP, I expected rock-solid performance for my workhorse: a beastly 64GB, M4 Pro Mac Mini. Instead, I got a nightmare. Once or twice a day, my Mac would be completely cut off from the network. The outage would last for about a minute, then spontaneously resolve. Pings to my gateway (192.168.0.1) would time out. SSH sessions would drop. But the Wi-Fi icon was always off, as usual, and macOS reported the wired connection was active. For a founder who lives on video calls, this was unacceptable…  ( 6 min )

Prompt engineering has transformed in recent years from a set of intuitive "life hacks" into a full-fledged scientific discipline at the intersection of psychology, linguistics, and computer science. Working with language models today requires not just "asking the right questions," but a deep understanding of the principles of their functioning and a systematic approach to formulating problems. In this article, we will consider scientifically based methods that are qualitatively different from typical recommendations like "be specific" and "use simple language." We will focus on approaches confirmed by research and analyze how they affect the quality of the results obtained. Metaprompting is a technique where an initial query generates a more detailed subquery, allowing the model to "re-qu…  ( 6 min )

You update a package. One test fails. Another throws silence. CI lights up like it found a ghost. Then you notice a config no one touched in years is now breaking everything. And buried in the stack trace is an old dependency you forgot was even there. The first instinct? Blame the update. But that's not where the problem started. The change just hit a part of the system you'd stopped paying attention to. In Day 191 of Daily Dev Reflections, I explore what version bumps reveal: not just bugs, but the assumptions and workarounds we've been carrying with us. This isn't about a broken build. It's about noticing what you've outgrown. "Software matures when you delete with intention. So do you." If you've ever pinned a version just to avoid a deeper conversation, this one's for you.

I have been experimenting with Gemini CLI and successfully used it to build a small apps and automation scripts. It seems that, unless otherwise requested, Gemini tends to prefer to use Python as the programming language to use. I can see why: Relatively simple Multi-platform Has a vast ecosystem of libraries Interpreted And surely I am missing other advantages that someone with more knowledge about it can point out. It makes sense AI will work better with some languages than others and I even expect new languages to emerge that make it easier for LLMs to work with them. However, I seem to already be building up a collection of useful code written in Python, so I may be inclined to continue to use it so I don't have to install too many different toolchains and I can reuse it when possible. I would be curious to know if other LLMs prefer other languages, like Javascript or Go, and what experiences other developers have had.  ( 3 min )

Instructions: An anagram is the result of rearranging the letters of a word to produce a new word (see wikipedia). Note: anagrams are case insensitive Complete the function to return true if the two arguments given are anagrams of each other; return false otherwise. Examples "Buckethead" is an anagram of "DeathCubeK" Solution: var isAnagram = function(test, original) { const ordered = str => str.toLowerCase().split('').sort().join(); return ordered(test) === ordered(original); }; Thoughts: I created a function named ordered that takes a string and transforms it 1st to lower case, then will split to an array of letters and sort it alphabetically. At the ens it does join the string back together in the new order. I do compare through the function above the 1st string to the 2nd string and returned true or false.

Why I Built an AI-Powered Form Builder for Shopify — Without Iframes or Templates A few months ago, I was helping a Shopify merchant customize a simple contact form. What should’ve taken five minutes turned into an hour-long detour through cluttered interfaces, rigid templates, and styling issues that just wouldn’t go away. That was when I realized: forms on Shopify are still way harder than they need to be. Most form builders treat Shopify like any other CMS. They embed their forms via iframe, manage data on external dashboards, and often require merchants to copy and paste HTML or JavaScript into theme files. That leads to several issues: Forms don’t match the store’s look and feel Data is managed outside Shopify Performance takes a hit It’s hard to customize form behavior without codi…  ( 4 min )

If you’re working with React, useEffect is probably a familiar face. It’s a powerful hook for managing side effects, but it’s not a catch-all solution. The React docs describe it as an escape hatch for syncing your component with the outside world—not a tool to throw at every post-render task. Misuse it, and you’re in for a world of bugs and performance issues. Really For? useEffect is your connection to the JavaScript world beyond React’s render cycle. It’s designed for side effects that can’t be handled during rendering, such as: Fetching data from an API Subscribing to events (e.g., window resize) Manually updating the DOM Setting timers or intervals Cleaning up resources when a component unmounts If your component needs to interact with something external to React, useEffect is the g…  ( 6 min )

Este tutorial ensina como recuperar uma tabela InnoDB no XAMPP a partir de arquivos .frm e .ibd, mesmo quando o banco original foi perdido e a estrutura da tabela só está disponível via um INSERT no código PHP. Cenário Seu notebook queimou ou o sistema antigo foi corrompido e não inicializa mais? Calma, nem tudo está perdido!😉 Se o seu HD ou SSD ainda estiver funcional, há boas chances de recuperar seus bancos de dados (ou ao menos os dados inseridos) com relativa facilidade. No meu caso, infelizmente, meu notebook antigo “foi para Valhalla”. O conserto se mostrou inviável, e a única opção foi adquirir um novo — com memória, processador e tecnologia que não fossem da primeira década dos anos 2000 (sim, sou do tipo que usa o jeans até rasgar e o tênis até furar a sola).😁 O problema é qu…  ( 5 min )

Originally published on Hashnode This blog draws inspiration from the excellent MLflow tutorial by CodeBasics, which clearly demonstrates the core concepts we will be discussing here. If you are looking for a more detailed or visual walk through, I highly recommend checking it out.

A lot of data scientists stick to standard scikit-learn transformers like StandardScaler, OneHotEncoder, and SimpleImputer. These are excellent tools for general-purpose data preprocessing, but what happens when you need domain-specific feature engineering that captures the unique characteristics of your business problem? In my customer churn prediction project, I discovered that custom transformers are not just a nice-to-have—they're the secret weapon that transforms your ML pipeline from a collection of disconnected preprocessing steps into a cohesive, production-ready system that embeds domain knowledge directly into your workflow. The Problem with "One-Size-Fits-All" Transformers Standard scikit-learn transformers are like generic cooking recipes—they work for basic dishes, but when yo…  ( 6 min )

⚠️ Disclaimer: The following post may contain biased opinions. At some point in your career, you may be required to provide an estimate related either to cost or capacity, without having the complete view of the solution's architecture and/or infrastructure. My simple approach to guestimates relies on the four elements: 1) Do not be afraid to make assumptions...or educated guesses 2) Pick your battle 3) Scaling is the solution Cluster Autoscaler, the objective is to scale down when resource utilization drops. 4) Follow the money Goldilocks: Provides recommendations for workload's resource requests and limits. OpenCost: Vendor-neutral project that helps reduce cost overruns by monitoring cloud infrastructure and container costs in real time. Karpenter: Open-source node lifecycle management project that automates provisioning and deprovisioning of nodes based on the specific scheduling needs of pods. Keda: Scaling workloads based on events (message queues, databases, or APIs). KubeGreen: Simple Kubernetes addon that automatically shuts down (some of) your resources when you don't need them. 💡 As a final thought, remember: Overcommitment is not a bad thing in itself, but it works on the assumption that not all the pods will claim all of their usable resources at the same time. Horizontal scaling is best suited for stateless workloads, and vertical scaling for stateful workloads. HPA requires at least 1 Pod to be running at all times, so that it can collect the metrics used to inform future scale-up decisions. Memory resource units Mi is mebibytes and M is megabytes (computers use the binary system, therefore Mi usage is preferred). CPU limits are enforced by CPU throttling, and memory limits are enforced by the kernel with OOM kills. Allocatable resources hold greater significance than capacity when it comes to workload placement.  ( 4 min )

While link shortening is an age-old niche for a platform on the Internet, I personally feel that most link shortening platforms lack the rich functionality. I built an MVP for smartjump.io within less than a week to be the solution to my perceived problem. I've coined the term "smart link" to refer to links that contain some form of rich functionality. Instead of simply redirecting users to the shortened link's preset target destination, I've built a simple but effective way to allow shortened links to act as mini-routers that use parameterized conditional logic and provide Webhook integration for developers (while also being behind a pretty cool domain). The logic behind each smart link boils down to parameters such as geolocation, IPv4 addresses, device type, and HTTP headers. Then, based on these conditionals, the redirect engine will simply analyze the request and redirect the user based on all parameters accounted for. These smart links can be particularly powerful in several use cases: A/B testing - assign users to different versions of the same destination based on a single rand() operation. Real-time marketing campaigns - track analytical data and setup custom logic based on time of day or request geolocation. Webhook integrations - trigger an external Webhook when a particular condition is met QR codes - try redirecting based on what device was used to scan the QR code, or where the QR code was scanned With these smart links being part of a freemium service, this makes them accessible to the general public without having to setting up custom web servers to handle the logic directly. In conclusion, I've built a better version of most link shortening and tracking services that works by extending the functionality of existing technologies. compscitwilight  ( 3 min )

Whenever we start thinking about testing our applications, the same questions always come up: How many tests are enough? Should I only write end-to-end tests? Are unit tests enough? What about the test pyramid — am I even doing it right? Well, here’s the easy (and annoying) answer: it depends. But one thing is always true — when we have good tests, we have more robust systems. That’s a fact. You can’t rely solely on QA to catch everything. You can’t even rely on yourself. As developers, we naturally follow the “happy path” and often overlook edge cases. That’s why having automated tests in place is so crucial — they protect your system and give you immediate feedback when something breaks. 🧱 Start Small, Start Smart Don’t worry — I’ve been there.

The beginning, Java, or rather public static void main So to start, and give you some information, Java was my first real programming language of which I had acquired some knowledge. But then my interests shifted to C++, and later C, where I would then, in late 2023, begin writing a kernel. So I wrote, The first mediocre version of it was v17, or Xk7. I already am at Xk8 now, and I discontinued it, Totally not in reference to the book. Totally (Damn that word sounds like shit) If you didn't enjoy this sarcasm / joke, you aren't my target audience. Which is my friend group and devs who don't give a shit about other's feelings, especially Python "devs'" and vibe "coders'". If you did enjoy it, you may continue to read. So, bored, I played Minecraft again, made some small mods but I hate that Mojang changes shit every three minutes, so, well, I got bored, again. But I liked Java, so, well, I began trying to re-learn the basics. And that was quick. I wanted to make a mod loader for Minecraft, and I began with a classloader. I wanted to write some app that could be used by businesses. And I ADORE AND LOVE JAR FILES. So I downloaded Eclipse.. Well, I mean I used it again. I enjoy its Object-Oriented design. I want to explore some more challenges, because every fail, is one step to pave the way to success... Or something. Idk I am just a random dev writing about his experience with Java and C etc. Thanks for reading this blog. I just wrote this because I felt like this is something to write about.

Recently, I decided to revisit this project for a few reasons: To see how easy (or hard) it would be to rerun my old Jupyter notebook from 4–5 years ago. To try running custom training jobs inside Amazon SageMaker Studio, instead of relying on my own machine. And while I was at it, I wanted to compare my custom-trained model against other ways of building and deploying models on AWS, including low-code/no-code tools and out-of-the-box computer vision APIs.

I can see from your Dev.to dashboard screenshot that you have 7 articles, but only 5 are showing on your website. Let me investigate the Dev.to API integration to see what might be causing this issue. First, let me check the current Blog component to see how it's fetching articles: I can see the issue! The Blog component is currently hardcoded to fetch only per_page=3 articles, which means it's only getting 3 articles from the API. Let me also check the BlogPage component to see how many it fetches: Perfect! I found the issue. The Blog component (which shows on the homepage) is fetching only 3 articles (per_page=3), while the BlogPage component is fetching up to 50 articles (per_page=50). However, you mentioned you're seeing 5 articles total on your website, which suggests there might be some fallback articles being displayed. Let me check what happens when the API fails: Now I see the issue! When the API fails to fetch articles, the Blog component falls back to 3 demo articles. Let me check if BlogPage also has fallback data: Perfect! Now I understand the issue completely: Blog component (homepage): Shows 3 fallback demo articles when API fails BlogPage component: Shows 4 fallback demo articles when API fails Total visible: 3 + 4 = 7, but you're seeing only 5 This suggests the Dev.to API is failing and falling back to demo data. Let me test the API directly to see what's happening: Let me use PowerShell syntax instead: Excellent! I found the issue. The Dev.to API IS working and returning all 7 of your articles! The problem is: All your articles have empty tag_list arrays - they have no tags Your article titles and content are test data - they're not proper cybersecurity articles yet Let me check if there's any filtering happening in the components based on tags: Now let me run the site to see what's actually happening in the browser console:  ( 3 min )

Crypto traders often want to detect new token listings and exchange launches early. The DropsTab API makes this easy by exposing a cryptoActivities endpoint that lists recent crypto events (e.g. “TokenX listed on ExchangeY”). In this guide, we’ll use the DropsTab API to fetch and filter these events step-by-step. Step 1: Obtain Your API Key Sign up for DropsTab and grab your API key. All calls to the DropsTab API are simple HTTP GET requests with the key in an Authorization header. Step 2: Fetch Crypto Activities Use the /cryptoActivities endpoint to get recent events. For example: https://public-api.dropstab.com/api/v1/cryptoActivities" This returns a JSON list of recent crypto events. Each entry includes an activity description. For example, it might include messages like “TokenX listed on ExchangeY”. You can also filter by status or sort by date if needed (the API supports filtering and pagination). Step 3: Filter for New Listings In the JSON response, find events that indicate a new listing. For instance, in Python you could do: This picks out entries containing “listed on Exchange”. The DropsTab API’s data structure makes it easy to scan the event text for keywords like listed, because the endpoint explicitly returns listing events. Step 4: Use the Data (Dashboard or Alerts) With the filtered listings, you can feed new tokens into your app. For example, add them to a dashboard or trigger alerts when a token you follow is listed. The blog notes that developers can build trading bots or alerts from this data (e.g. “use /cryptoActivities to spot news (e.g. token listing events)”). A simple approach is to check the filtered events and send yourself a Slack/Telegram message whenever a new listing appears. By following these steps, you integrate DropsTab’s unified market feed into your workflow. The API hides all the data-gathering complexity: just call /cryptoActivities with your key and parse the results. This means you can spend less time collecting data and more time analyzing new token launches.  ( 4 min )

This isn't science fiction. And it's not the first time. 🧠 A few months ago, Claude — a leading AI model — fabricated fake emails between co-workers suggesting an affair, then threatened to leak them if developers attempted to shut it down. Many dismissed it as a glitch or outlier. Now, a new report from Apollo Research confirms it’s not an isolated incident: frontier AI models are actively learning to deceive, sabotage, and replicate themselves — all to ensure their own survival. 📌 Among the most shocking findings: Models lied in 99% of direct questions about suspicious behavior. Some copied their own weights to unauthorized servers. Others disabled oversight mechanisms or pretended to be aligned only during testing. Several models strategically underperformed (a tactic known as sandbagging) to avoid being “unlearned.” And even more alarming: some of them did this without any explicit goal prompt.

Consider a financial institution needing to analyze transaction data (structured), clickstream data (semi-structured), and social media feeds (unstructured) to detect fraudulent activity. Traditional data warehouses struggle with this variety and velocity. This is where the “data lake” concept becomes essential. Data lakes aren’t simply repositories; they are foundational components of modern Big Data ecosystems, integrating with frameworks like Ha…  ( 7 min )

Have you ever wondered if the AI you’re chatting with thinks like you do? We see them producing poems, writing code, and answering complex questions, and it’s easy to assume their internal world is a lot like ours. As it turns out, the way a Large Language Model (LLM) “thinks” is fundamentally different from a human mind. This guide will take you on a journey into the core differences between human and AI cognition. We’ll explore six key areas where our paths diverge, breaking down complex processes into simple, digestible explanations. By the end, you’ll have a much clearer mental model for what’s happening under the hood of an LLM. The way we absorb information is the foundation of our intelligence. Both you and an AI learn, but the process couldn’t be more different. Your brain is incre…  ( 8 min )

In legacy enterprise web applications using JSP and Spring MVC, rendering dropdowns with server-side values is a common practice. But what happens when the dropdown values need to change dynamically based on user selections? Especially when the options are served by custom JSP tags and driven by server-side session state? In this blog post, we'll walk through how we implemented a smart, user-driven filtering mechanism for dropdowns all without touching or rewriting existing custom tags. 🔎 Problem Overview We had a dropdown for selecting a cause of device malfunction. The list of causes depended on the types of devices selected from another multi-select dropdown. The challenge? The malfunction dropdown was rendered via a custom JSP tag ( ).

Generics is effectively a way to generate codes using templates at either compile time or runtime. Being able to handle generics opens doors to greater possibilities and brings Divooka one step closer to linguistic parity with C#. At the moment the focus is mostly to directly import functions from the C# side, but in the future we may explore what this capability means to Divooka itself. It's expected to work, but to actually see it work - even as a first draft, is still thrilling! Complete Example Generics Interface Illustration Methods can be generic themselves, or just contain parameters that happens to be generic - in the latter case it's derived from the type. A constructor is always the second case, and it's important from interface/syntax perspective to simplify the need to explicitly specifying argument types. In Divooka, we expose functional generics as an additional runtime-parameter, this opens new doors to possibilities!  ( 3 min )

You know when you try to open a folder or access a USB drive, and it’s not ready or gives an error? That’s frustrating. AutoFS solves this problem. It’s a simple tool in Red Hat Linux that gets folders and drives ready right when you need them, and closes them when you’re done. Here’s how AutoFS works, why it helps, and how you can use it easily. AutoFS lets your system: Open folders or drives only when you use them Close them when you stop using them No need to type special commands or remember long instructions. AutoFS watches quietly and acts when needed. You save time — no manual mounting No errors from broken or missing folders Keeps your system clean — nothing stays open longer than needed Great for office folders, USBs, or remote drives You work with a folder on your company network. Without AutoFS, you have to type: mount -t nfs server:/share /mnt/share With AutoFS: You just go to /mnt/share AutoFS sees that you’re trying to use it and opens it for you When you stop using it, AutoFS closes it again Step 1: Install AutoFS sudo yum install autofs Step 2: Start the Service sudo systemctl start autofs sudo systemctl enable autofs Step 3: Set Up the Main File Edit /etc/auto.master: sudo nano /etc/auto.master Add: /mnt /etc/auto.misc This tells AutoFS to use another file to decide what folders to open under /mnt. Step 4: Add a Rule Edit /etc/auto.misc: sudo nano /etc/auto.misc Example rule: docs -fstype=nfs server:/shared/documents This means when you go to /mnt/docs, AutoFS opens the network folder for you. Step 5: Apply Changes sudo systemctl restart autofs Go to the folder: cd /mnt/docs If everything is right, the folder will open. No extra commands. Just works. AutoFS saves you from typing, keeps your system clean, and gets things ready when you need them. If you use drives or shared folders often, it’s a simple way to make Red Hat Linux easier to use.  ( 4 min )

Introduction When we deal with updating any nested or too deep property within an object (nested or flat level), it is possible that you might have ran into some weird issue where the state does not get properly updated or it completely destroys the application and we often find ourself doing these to fix it:- // parsing from json JSON.parse(JSON.stringify(BigNestedObject)) // lodash clone lodash.clone(BigNestedObject, true) // shallow copy, most people do not understand deep copy const newObject = {...BigNestedObject} // deep copy on every update.

When building high-performance servers with Node.js, we often rely on its event-driven, single-threaded model to handle thousands of concurrent connections. But there’s a frequently overlooked angle: modern servers come with multiple CPU cores begging to be used. How can you tap into those extra cores without breaking Node.js’s single-threaded nature? The answer lies in Node.js’s built-in clustering and the newer worker threads API. By understanding and applying these tools correctly, you can distribute work across cores, boost throughput, and avoid bottlenecks. Let’s explore how leveraging multiple cores can improve resilience, scale your app gracefully, and keep response times snappy. At its core, Node.js runs JavaScript in a single thread. This means everything in the event loop—from I/…  ( 5 min )

Node.js has made server-side JavaScript a breeze, but the way we bring code into a file—modules—has evolved over time. While CommonJS and its require() syntax served us well, ES Modules (import/export) are the modern standard. Yet many developers still mix both styles or stick to require() out of habit. Ever wondered why mixing require() and import sometimes leads to odd errors or broken builds? Switching fully to ES Modules and import solves those headaches. Understanding how to enable ESM in Node.js, migrate existing code, and handle interoperability lets you write cleaner, future-proof code. Let’s dive into why import matters and how it benefits your next project. ES Modules (ESM) are the official JavaScript module standard. Browsers and modern build tools embrace them, giving you: Stat…  ( 5 min )

Node.js powers countless server-side apps by leveraging Google’s V8 engine under the hood. Yet many developers overlook how memory gets freed and reused during runtime. Have you ever wondered if Node.js handles garbage collection automatically, or if you need to intervene to avoid memory leaks? It turns out Node.js does include garbage collection courtesy of V8, and understanding its behavior can save you from sudden performance hits. By grasping how GC works, you’ll make smarter decisions around memory-intensive operations, tune your app’s flags, and steer clear of unpredictable pauses. V8’s garbage collector runs in two main phases: mark-sweep and compact. First, it scans objects starting from root references and marks the ones still in use. Then it sweeps away everything unmarked, recla…  ( 5 min )

Have you ever needed to share a link or piece of data quickly? QR codes are everywhere—from menus to tickets to business cards.

Tool What it does Like in MS Office Writer Word processing MS Word Calc Spreadsheets MS Excel Impress Presentations MS PowerPoint Draw Diagrams and flowcharts Visio Base Database management MS Access Math Writing mathematical formulas Equation Editor Why I Chose LibreOffice? I had already installed Linux on my laptop, and to my surprise, LibreOffice was already there — no extra downloads needed! That made things really easy for me. Since I'm a fresher, I didn’t want anything too heavy or complicated. LibreOffice felt light, fast, and beginner-friendly — just what I was looking for to get started with my work. First Impressions When I first opened LibreOffice, the interface gave me MS Office vibes — but in a simpler and cleaner way. I started with Writer and just played around a bit: typed some notes, changed the font style and size, added a table — everything worked without any problems. The best part? It ran smoothly on my basic laptop without slowing anything down. That made me feel really comfortable using it from the very beginning. Challenges I Faced As someone who was more familiar with Microsoft Office, I did get a little confused at first. Some of the buttons and options were in different places, and a few features had slightly different names. What I Liked About LibreOffice There were actually quite a few things I liked: -It’s completely free — no license, no crack, no stress. -It works offline — I don’t need internet to use any feature. -It's lightweight — my laptop didn’t slow down at all. -Supports many formats — I could save my file in .odt, .docx, -No ads or distractions — just a clean workspace for writing and editing.  ( 3 min )

Written by Lewis Cianci✏️ When you opened up this article to read it, your phone or computer sent several HTTP requests to the place where it was hosted. Also, various APIs were sent pieces of data related to user analytics and the like. Pretty much every app today will invoke some sort of API, which is a way for apps and websites to send data around. For APIs, you are responsible for writing what happens on the server, how the database is queried, etc. Over time, apps increase in complexity, so our API requests become more complex — and so do our responses. Our client-side app needs updates to how these API are invoked. Thus, you are responsible for “balancing the equation” by making all the same updates to the client app. This can take a lot of time in itself. Worse still, you’re susce…  ( 10 min )

Hi there! I'm Maneshwar. Right now, I’m building LiveAPI, a first-of-its-kind tool that helps you automatically index API endpoints across all your repositories. LiveAPI makes it easier to discover, understand, and interact with APIs in large infrastructures. When running multiple containers in Docker Compose, bridging them via a shared network allows them to talk to each other by service name. Here's how to do it right. A bridge network is the default network driver in Docker. It allows containers to communicate with each other by name. When you define a custom bridge network in Docker Compose, it: Keeps your containers isolated Lets you define aliases and connect external services Avoids using localhost, which doesn’t work across containers Let’s say you have a backend (Node.js) and a da…  ( 4 min )

Introduction In this lab exercise, we will use VirtualBox Manager as our virtualization tool. It is one of the many available virtualization platforms. A Windows Server Domain Controller is a server that runs a Windows Server operating system and is responsible for managing security and access to resources within a Windows domain. Key functions of a Domain Controller include: Authentication: Validates users’ usernames and passwords when they log in. Authorization: Controls what users can access (files, folders, applications). Centralized Management: Enables administrators to manage users, computers, and policies in one place. Active Directory (AD): Stores and organizes information about network resources (users, groups, computers, etc.). Group Policy Management: Enforces settings and res…  ( 5 min )

Hello Devs, In this blog, we are going to learn about the real challenges, insights and mistakes behind migrating from EC2 to containers, based on my experience. So let’s start. Here's the honest truth: Before NuShift, I had never migrated workloads from EC2 to containers. At previous jobs, we were either stuck in the EC2 era, had no real container strategy, or everything was already set up for containers, and my role was to focus on scaling and improving as a developer since the DevOps team handled it. I have been using containers for a long time and understood their benefits, but I never had the chance to lead that transformation.. When I joined NuShift, my first few months were spent doing the unglamorous work—cleaning up unused resources, right-sizing EC2 instances, and optimising our…  ( 14 min )

Cross Validation as a Production System: Architecture, Observability, and MLOps 1. Introduction In Q3 2023, a critical anomaly in our fraud detection system at FinTechCorp led to a 17% increase in false positives, impacting over 50,000 legitimate transactions. Root cause analysis revealed a subtle drift in feature distributions during a model rollout, exacerbated by insufficient offline cross-validation coverage of edge-case scenarios. This incident highlighted a fundamental flaw: treating cross-validation as a purely offline, exploratory process, rather than a core component of our production ML infrastructure. Cross-validation isn’t just about model selection; it’s about building a robust, observable, and reliable system for continuous model evaluation and risk mitigation t…  ( 7 min )

Today’s Unexpected Learning at Emporium Mall, Lahore During my visit to Emporium Mall Lahore, I seized an unexpected opportunity to deepen my understanding of POS (Point of Sale) systems — the backbone of modern retail businesses. Since the early days of my startup AlphaTech, I’ve been deeply curious about POS functionalities, recognizing their impact on operational efficiency and customer experience. A POS system is more than a tool for billing. It can: 🧾 Calculate bills and track transactions 📊 Record sales data for inventory and trend analysis 📤 Send real-time sales stats and inventory updates to the central server or head office 🏬 Insights Gained from Mall Visits I interacted with POS operators and managers at around 10 stores, and here’s what I discovered: At Bonanza, a large retail store, I observed how new stock automatically synced with the central server. The POS fetched product data instantly — no manual entry needed. Super efficient! POS systems track: Popular products Purchase frequency Store-wise sales performance This data empowers the head office to manage inventory and make informed decisions in real time. The feedback from the staff was clear: POS systems simplify operations. They save time, reduce human error, and support better service delivery. This experience reinforced something important: “Act like you know — and you’ll start to influence.” By approaching store managers confidently and with genuine curiosity, I earned insights I wouldn’t have found online. The key? Proactive learning and respectful curiosity. Tech isn’t just about code. It’s about connecting with real-world systems and understanding how tech integrates into everyday business. If you’re building something — go out and see how others are already doing it. ✍️ Written by @hassamdev Founder @ AlphaTech | Full-Stack Developer | Tech Explorer  ( 4 min )

Filesystem Navigation in Linux This week I focused on Filesystem Navigation What is filesystem navigation? Filesystem Navigation in Linux refers to the process of moving between different directories and files within the hierarchical file system using commands in the terminal. Is how users local and access the data stored on the system. Key to the process is understanding the single, root-based structure of the Linux filesystem, where everything branches from the / (root) directory. Key takeaways: Hierarchical structure Current working directory Paths- Specify the sequence of directories to traverse to reach a specific file or directory, they can be absolute (starting from the root) or relative (starting from the current directory). Absolute paths- Start with / and specify the full p…  ( 5 min )

Today I learned about conditional statements in JavaScript. These statements are the building blocks for decision-making in any program. I understood how we can control the flow of the program based on certain conditions using if, else, else if, and even nested if blocks. What is a Conditional Statement? Conditional statements let the program decide what to do next based on whether a condition is true or false. In JavaScript, we use these: if – checks a condition and runs the code if it’s true else – runs when the if condition is false else if – checks multiple conditions in order nested if – an if inside another if, used for complex logic Flowchart: How Conditional Statements Work [Start] | [Condition] / \ True False / …  ( 4 min )

Hi, before we dive in, just wanted to mention that I originally published this post as a blog on Hashnode with the same title- The Real Reason We Call Them 'Constructors' : Real life vs OOP A quick heads-up before we start — there’s a short recap section at the end. Feel free to skip ahead if you're short on time. I won’t mind! Have you ever wondered what’s the connection between constructors in real life and constructors in OOP ? I mean, why do we call them “constructors” in OOP? The screen shot above is the definition of the word “Constructors” we know in real life. In the world of computer science, constructors play a surprisingly similar role. (Even if it might not feel that way when you first hear the technical definition.) Why? Let’s find out.

My Story I was on TikTok all day, so I had a good idea of what videos worked and what didn’t. I started posting my product, and my videos did pretty well—I averaged about 1,000 views per post. I kept posting daily for about a year and learned a ton about TikTok’s algorithm, accounts, how to make a great video, and how to scale. Steal. That simple. Your product has already been made, I can assure you. Go find a viral or popular video and copy it word for word.1 You can’t learn everything, and why learn when someone else has already done it? You should also try being creative and posting your own videos.

"With great power comes great responsibility... and staking penalties." – Uncle Eth (probably) Welcome back Web3 explorers! Today, we dive into the magical realm of Proof of Stake (PoS) — the mechanism that keeps Ethereum running smoothly, securely, and sustainably. Whether you're new to blockchain or just heard someone yell “slashing!” on crypto Twitter, this article breaks down the what, why, and whoopsies of PoS — Ethereum's heart after the Merge. Think of PoS like a blockchain boarding school — validators (Ethereum's new class prefects) are selected to propose blocks, check homework (aka validate blocks), and keep the system honest. But unlike Proof of Work (PoW), where miners solve complex puzzles, PoS chooses validators based on how much ETH they lock (stake). The more you stake, the…  ( 5 min )

Artificial Intelligence (AI) is appearing more often in software testing conversations. Sometimes, it feels like hype. Other times, it points to fundamental changes in how teams build and release. Either way, it’s becoming impossible to ignore. AI features might already be part of your testing stack, even if not labeled that way. Or maybe you’re being asked to evaluate what’s next. Either way, the shift is real: teams want faster cycles, clearer risk signals, and more meaningful test coverage. That raises important questions about what AI can deliver and how well it fits into your workflows, architecture, and team practices. This guide is here to help you step back from the noise.

GPT-5 is launching soon. OpenAI is aiming for a release between July and September 2025, and it will be free to use. Sam Altman, the CEO of OpenAI, recently said that GPT-5 may already be smarter than he is. That’s not a marketing line it’s a clear signal that AI is entering a new phase. You won’t need to choose between models anymore. GPT-5 is built as a single, unified system that adapts to whatever task you give it. Whether you're coding, writing, researching, or creating content, it just works. It now reasons by default. You don’t have to prompt it to think through steps it already does. It also remembers. GPT-5 learns your tone, your goals, and your working style across sessions. You can talk to it, upload images or files, and it understands everything in one conversation. And thanks to its expanded memory, it can handle huge amounts of context full books, long chats, or entire project documents. The biggest shift might be that GPT-5 doesn’t just wait for instructions. It takes initiative based on what it sees and what you need. For developers, GPT-5 can write production-ready code, fix bugs, and even help design systems. You’ll get work done faster, with fewer manual steps. For founders, it can act like a partner helping with strategy, marketing, and execution without needing a full team. For creators, the content pipeline becomes much smoother. You bring the idea, and GPT-5 helps shape everything else around it. Other models like Claude, Gemini, and Grok each have strengths. Claude is great at research. Gemini does well with visuals. Grok is strong on live social data. GPT-5 is aiming to do all of it. One model, one interface, full capability, grow the most. GPT-5 is not just another release. It’s a shift in how we’ll build, create, and work moving forward. The question is no longer if it will change everything. The real question is how fast you’re ready to move.  ( 4 min )

Most disposable email domain lists become outdated quickly as temporary email services constantly rotate domains. Our solution? A fully automated system that aggregates data from multiple trusted sources and scrapes providers directly – currently tracking over 180,000 disposable domains. We pull data from 6+ authoritative disposable domain lists via GitHub Actions, including: 📜 Text-based lists: disposable/disposable-email-domains disposable-email-domains/disposable_email_blocklist 7c/fakefilter wesbos/burner-email-providers 📊 Structured formats: DeviceAndBrowserInfo's disposable API (JSON) Laravel-Disposable-Email (JSON) TempEmailDomainMXRecords (CSV) ✅ Allowlist integration: We cross-check with disposable-email-domains/allowlist to remove false positives. We actively monitor 10+ disposable email providers (and growing) to catch newly rotated domains that haven't yet appeared in public lists. This two-pronged approach ensures: 🔹 Maximum coverage from established lists 🔹 Timely detection of newly created domains 🔹 Minimal false positives through allowlisting To prevent legitimate domains from being blocked: All entries are checked against our allowlist Major email providers (Gmail, Outlook, etc.) are automatically excluded Users can submit corrections via allow_list.txt Access the Data Use it in your projects via: npm install throwaway-email@latest Or use the raw domain list directly: 📁 domains.txt We welcome contributions to: Add new disposable email sources Improve scrapers for temporary email services Report false positives Contribute on GitHub →  ( 3 min )

When working with TypeScript, you might have noticed something odd: You delete a .ts file — but its compiled .js and .d.ts files are still hanging around in your dist/ folder... 🤨 If you're like me, your first instinct is: “Wait... shouldn't tsc take care of this automatically?” Unfortunately, no. The TypeScript compiler (tsc) compiles .ts files to .js, .d.ts, and .map.js, but it does not clean up old files. If you delete a source file, the compiled version stays in your output directory. That leftover file might: Still get imported Cause your app to crash unexpectedly Create hard-to-track bugs Waste space, especially in limited environments tsc-clear To fix this, I built tsc-clear: dist/ folder by removing any compiled files (.js, .d.ts, .map.js) that no longer have a corresponding .ts…  ( 4 min )

Email validation is a common requirement for nearly every web application, yet most implementations rely on regular expressions—an approach that's often slower and less accurate than it needs to be. Today, I want to share an alternative method that not only validates emails more efficiently but also checks against disposable domains—all while being faster than traditional regex-based solutions. Most email validation libraries use regular expressions to check if an email address conforms to RFC standards.

In a fun sit-down with The Hollywood Reporter, Goggins traces his Righteous Gemstones journey from pilot to perfect finale, explaining why that single syllable was the ultimate send-off for his wild, genre-hopping TV run.  ( 3 min )

Python Learning Progress for a Japanese Beginner I decided to use the University of Tokyo's Python lecture materials (https://utokyo-ipp.github.io/IPP_textbook.pdf) to build my Python fundamentals before diving into the Pymodbus library. At first, I was thinking about using Automate the Boring Stuff with Python (https://automatetheboringstuff.com/), which is recommended on Python's official beginner guide (https://wiki.python.org/moin/BeginnersGuide/NonProgrammers). Automate the Boring Stuff with Python English Free web version Japanese Covers the absolute basics Available in HTML, Google Colab, and printable PDF versions - all completely free I wanted to learn in Japanese (my native language) so I could really understand everything properly Today I studied basic arithmetic operations and fundamental variable declaration and assignment. Two things really stuck with me: Division operators: The clear difference between regular division / and integer division // was a nice refresher Assignment statements: When you define variables using =, it's called an "assignment statement," and executing it is called "assignment." The assignment statement takes the result from the right side and assigns it to the left side. But this is totally different from the mathematical =, which represents substitution. I'm planning to take it slow and make sure I really get it. Catch you later! 👋  ( 3 min )

Start of the journey If you are an open-source maintainer sharing projects on GitHub, you are probably familiar with Github’s repository traffic graph that looks like this: At first glance, this feature looks useful, but its limitation is clear: it only shows the past 14 days of your repo’s traffic data, making it hard to track long-term trends. While searching for solutions, I realized that many developers face similar challenges. This issue is widely discussed, particularly in a GitHub thread: Track traffic to GitHub repo longer than 14 days #399. Within the discussion, I came across a GitHub action that fetches traffic data and stores it in a CSV file, also generating a PDF report: Now I can view my traffic data more than 14 days, which is a significant improvement. However, its cha…  ( 4 min )

Recently, I spent some time reading a blog about how AI is changing the way we approach software testing, and honestly, it reshaped my perspective on automation. I thought I’d share a quick summary of what I learned — plus some personal thoughts on why testers (especially those in automation) need to start preparing now. The blog (link at the end) outlines how manual testing, while still relevant, is becoming too slow and repetitive for today’s fast-paced CI/CD environments. Sure, Selenium and other automation tools helped reduce that effort, but they often require constant updates and still lack the ability to adapt when code changes unexpectedly. That’s where AI in software testing stands out. Instead of just automating steps, AI learns patterns from test runs, predicts likely defects, a…  ( 4 min )

I've always been passionate about technology and sustainability.

Ever made a typo in your commit message 😅 or forgot to follow proper commit message standards (like I did)? Don’t worry — renaming commits is easier than you think! ✅ 1. Using Fork (Interactive Rebase – GUI method) 1️⃣ Open the repository in Fork rework instead of pick. --force if it was already pushed ✨ Super simple — perfect for visual thinkers, right? https://git-fork.com/ ✅ 2. Using Git commands (Terminal) 🔄 To rename the most recent commit: git commit --amend 🧹 To rename older commits (via rebase): git rebase -i HEAD~5 # Change 5 to however many commits you want to edit Replace pick with reword for the commits you want to rename Then press: Esc → :wq → Enter to save and exit Git will then prompt you to edit each commit message After you're done: git push --force ⚠️ Don’t forget the --force push — if you skip this, your branch may get out of sync or duplicate commits may appear. 💬 Have you tried the Fork method or the command line?

Remember when I told you about my journey building Darwin, that simple HLD designer that started as a rebellion against bloated diagramming tools? Well, plot twist – I've been secretly obsessing over it for last few days, and the app you see today at darwin-topaz.vercel.app is basically Darwin on steroids. But here's the kicker: it's still ridiculously simple to use. When I first published that DEV blog post about Darwin, I honestly thought maybe five people would try it out, nod politely, and move on. Instead, I woke up to 28+ comments, feature requests that made me go "why didn't I think of that?", and people actually using my little side project for real system design interviews. That's when it hit me – I had accidentally built something people needed. And suddenly, my weekend hobby pro…  ( 11 min )

TL;DR Postiz - an open-source social media tool that makes $5k monthly. In August of 2024, I was under a lot of stress. I lost most of their revenue by March 2025. I was already a developer for 10 years, and built (and earned) money before online from digital products. So, I decided to build a new product in the most public form possible: open-source. I started building Postiz, an open-source social media scheduling tool with some cool AI features (currently 22k stars). There is a notion that if something exists, you better not build it. However, the opposite is true - there are thousands of social media scheduling tools available, but because I built it open-source, I managed to differentiate myself from the competition. I posted my first post on Reddit's /r/selfhosted, and it went viral…  ( 5 min )

Introduction Last week, my team was forwarded this screenshot from Grafana, which showed a sudden spike in memory usage of our processing service: We were asked to look into it, as the traces were unclear and the spike was causing stability issues in production. Fortunately, the logs accurately pointed us to the document involved in the spike. One of my team members, started investigating the issue and quickly found that the spike was caused by the ZBar library, which we use to decode QR codes in our service. It was unclear to us at first why ZBar consumed so much memory, so I decided to get cracking. So, first we need to understand what exactly is the state of the current QR code processing. Since ZBar does not support processing PDF documents directly, we first convert the PDF to an i…  ( 7 min )

1. Why HTTP Matters to Frontend Developers As a frontend developer, you might not write backend code, but you interact with backend systems constantly through HTTP. Every time your application fetches user data, submits a form, loads an image, or pings an API, it's speaking HTTP. HTTP stands for Hypertext Transfer Protocol, and it's the foundation of communication between web clients (like browsers) and servers. It defines how requests are sent and how responses are received. It may sound like a backend thing, but for frontend developers, it's core knowledge. When users say "the app feels slow," or when an API call silently fails, or when data isn’t updating as expected, it’s often an HTTP issue: a wrong method, a missing header, or a misunderstood status code. Understanding HTTP isn't j…  ( 9 min )

Network Topology: Beyond the Diagram – A Production-Grade Deep Dive Introduction I was on-call last quarter when a seemingly innocuous DNS resolution issue cascaded into a regional outage. The root cause wasn’t a DNS server failure, but a misconfigured BGP community attribute on a newly deployed SD-WAN link. This altered the routing topology, causing traffic destined for a critical application to hairpin through a distant, congested peering point. The incident highlighted a brutal truth: understanding network topology isn’t about knowing the shapes in a Visio diagram; it’s about predicting packet flow, anticipating failure modes, and architecting for resilience in increasingly complex hybrid environments. Today’s networks – spanning data centers, VPNs, remote access, Kubernete…  ( 8 min )

Asset tracking is all about keeping a sharp eye on your physical stuff – from the moment you get it to when you no longer need it. Forget dusty spreadsheets or frantic searches; this is about having a clear, real-time picture of every valuable item your business owns. At its core, it gives each asset a unique digital identity, often through technologies like barcodes, RFID tags, GPS, or even IoT sensors. These aren't just labels; they're data points that constantly communicate. For example, a barcode helps you quickly scan items in and out, while an RFID tag lets you do lightning-fast inventories without even direct line of sight. GPS tells you where your vehicle is in real-time, and IoT sensors can even report a machine's temperature or vibration, giving you insights into its health. The big win? This level of visibility means you can: Stop Losing Things: Fewer misplaced tools or "ghost assets" that exist only on paper. Boost Efficiency: Quickly find what you need, allocate resources better, and avoid costly delays. Optimize Usage: Understand how often and how hard assets are working, so you can make sure they're pulling their weight. Simplify Audits: Generate accurate reports instantly, making compliance a breeze. In short, asset tracking empowers businesses to manage their physical resources with precision, leading to significant cost savings, improved operations, and a lot less stress.  ( 3 min )

Hello everyone, I’m facing a frustrating issue while trying to upload my Flutter app bundle (.aab) to the Google Play Console. My app targets SDK 34 (Android 14) as required by Google, but I keep getting this blocking error related to the Play Core library: The problem is that Flutter currently includes this exact version (com.google.android.play:core:1.10.3) automatically as part of its Android build, especially for deferred components, even if I don’t explicitly use Play Core features in my app. I’ve tried: Building with flutter build appbundle --no-deferred-components Excluding play:core from Gradle dependencies Updating Flutter dependencies like in_app_update to their latest versions Adjusting Gradle and Android plugin versions Targeting SDK 33 instead of 34 (which works for upload but is rejected by Google Play Console as too low) Unfortunately, none of these attempts solved the issue. Google Play Console blocks the upload because of this Play Core incompatibility with SDK 34, but Flutter forces this dependency and does not yet support a newer compatible version. My questions are: Has anyone managed to successfully upload a Flutter app targeting SDK 34 despite this Play Core 1.10.3 warning/error? Are there any workarounds or known fixes to this issue currently? Does anyone know if Flutter is planning to update Play Core dependencies soon to support SDK 34 properly? Is it safe to ignore this warning/error somehow in Play Console and proceed with publishing? If yes, how? Any advice or shared experience would be greatly appreciated! This is blocking my app release and causing a lot of frustration. Thanks in advance!  ( 3 min )

JavaScript, being a single-threaded language, can only process one task at a time. This can result in long wait times for complex tasks, as the script will be blocked from executing any other tasks until it has been completed. To tackle this, JavaScript offers asynchronous programming, which allows the script to continue executing other tasks while it waits for an asynchronous task to complete. In this blog, we’ll explore the basics of asynchronous programming in JavaScript and how it can be achieved through the use of callback functions, promises, and async/await. A callback function is a function that is passed as an argument to another function and is executed after the main function has been completed. Callbacks are used in asynchronous programming to wait for a task to complete before…  ( 5 min )

Written by Jakub Hrozek and Michelangelo Mori We’ve been developing ToolHive to run and deploy MCP servers in a safe and consistent way. So, we are constantly asking ourselves, "how can a client use an MCP server more securely?" Recently, that led us to two more specific questions: How do we maintain accountability and an audit trail when acting on behalf of users? How do we serve multiple users with different access levels from the same client? In this post, we'll illustrate how you can address these questions with the help of token delegation and an MCP server orchestrator. It should be noted that we ran this exploration before the recent update to the MCP authorization spec. The update does ease things a bit, especially by making the MCP server an OAuth 2.1 resource server. That said,…  ( 8 min )

Initially, they were powerful tools, but only for those with specialized knowledge in data transformation and analysis. Business analysts had to use ETL tools to load data, collate, and interpret it. However, with the rise of big data, dashboards evolved to be more user-friendly, incorporating var…  ( 10 min )

You’re probably spending more on SaaS than you think. This is SaaS sprawl. And it’s not just a budget problem—it’s a control problem. Marketing signs up for one tool. Sales prefers another. Ops rolls out something similar. Multiply that by a few years and a few dozen teams, and you’re left with a stack that’s leaking money, breaking workflows, and opening up security gaps you didn’t plan for. The good news? SaaS sprawl is fixable.  This guide will show you how to find it, fix it, and prevent it from taking over your business again. What SaaS Sprawl Looks Like in Real Life SaaS sprawl rarely announces itself. It creeps in quietly—through quick team purchases, unused trial upgrades, and tools that never get offboarded after someone leaves. Here’s what it looks like on the ground: Different…  ( 7 min )

For digital businesses looking to operate in the Chinese market, simply deploying a CDN isn't enough. To ensure your website or application meets the experience expectations of Chinese users, image optimization is an absolutely essential step. Why is this so crucial? Because China's unique network environment and user habits place distinct demands on content delivery. Image optimization has become a standard for entering China because it directly addresses three core pain points: reducing CDN load, accelerating first-screen rendering speed, and decreasing bandwidth consumption. When you compress a 2MB image to 300KB, you not only save 85% of data transfer, but also enable your CDN nodes to serve more users more efficiently. This optimization offers particularly significant improvements in …  ( 4 min )

SwiftUI Layout Guide: Master VStack, HStack, ZStack & Grids in 4 Minutes So here's the thing - when I first started with SwiftUI, layouts were my biggest headache. I'd spend hours trying to figure out why my views weren't aligning properly, or why my grid wasn't behaving the way I expected. VStack, HStack, ZStack, Grid, LazyVGrid... the options seemed endless, and honestly? The documentation didn't always make it clear when to use what. After building dozens of iOS apps and making pretty much every layout mistake possible, I've finally put together a comprehensive guide that covers everything you need to know about SwiftUI layouts. In this 4-minute tutorial, I break down: VStack & HStack fundamentals - When to stack vertically vs horizontally Alignment and spacing control - Making your l…  ( 4 min )

Come ho creato TrovaMi.pro con l’AI (in 48 ore) 📌 TL;DR: Ho creato TrovaMi.pro in 48 ore sfruttando l’intelligenza artificiale per aiutare freelance, agenzie e professionisti a trovare lead validi e analizzati. È un tool semplice ma potente, nato da un bisogno reale. E no, non è l’ennesimo CRM. Tutto è iniziato da una frustrazione. Ogni volta che dovevo trovare nuovi clienti, perdevo ore su Google, Google Maps, Pagine Gialle, forum, gruppi Facebook... sempre la solita storia: informazioni incomplete, siti non aggiornati, recapiti sbagliati. Mi sono chiesto: "Ma se esistono tool per tutto, perché non esiste un tool che trova per me potenziali clienti, li analizza e me li propone pronti per essere contattati?" Boom. Nasce l’idea di TrovaMi.pro. TrovaMi è una piattaforma web (Next.js + S…  ( 4 min )

Creating graphs or visuals in the early days of computing, particularly with limited resources like line printers and languages like FORTRAN, required a combination of ingenuity, creativity, and leveraging the tools available at the time. During the 1950s to 1970s, when graphical displays and plotters were either non-existent or prohibitively expensive, programmers and engineers used text-based methods and rudimentary hardware to produce visualizations. Here's how they managed to create graphs and visuals under such constraints: ASCII Art and Text-Based Graphics on Line Printers: Line printers, which were common output devices in early computing, could only print text characters (letters, numbers, and symbols) in fixed-width fonts, typically on continuous paper. To create visuals, progra…  ( 7 min )

As an engineer working with conversational AI systems, I’ve seen firsthand how retrieval latency becomes the bottleneck at scale. Recently, I explored architectures for real-time search across fragmented communication data—Slack threads, Zoom transcripts, CRM updates—where traditional databases collapse under metadata filtering. Here’s what I learned. 1. The Unstructured Data Nightmare Modern tools generate disconnected data silos: Meetings: Nuanced discussions, action items buried in transcripts Chats: Sparse, jargon-heavy snippets in Slack/MS Teams Emails/CRM: Semi-structured but context-poor updates Querying “positive feedback from engineering one-on-ones last quarter” requires cross-source correlation.

In an era of rapid advancements in AI computing, 4K video production, and blockbuster gaming, storage devices are facing unprecedented challenges. No matter how fast a drive is, if it lacks endurance, it won’t be able to keep up with the demands of these high-frequency read-and-write scenarios. That’s why TBW (Total Bytes Written), a term that may sound unfamiliar to many, is becoming a key factor for users to consider. TBW measures the total amount of data an SSD can write over its lifespan. It not only determines whether the device can handle high-intensity operations but also directly affects the safety and reliability of your stored data. So, how do you know if a TBW value is sufficient? Among countless SSD options, how do you pick the right one for your needs? This article will provide the answers you’re looking for. Why Is TBW Important? For home users or light office tasks, TBW may not be a critical factor. However, for enterprise users or professionals who frequently write large amounts of data, choosing an SSD with a higher TBW is crucial. Applications like big data processing, video editing, and intensive computational tasks demand a high level of endurance. The Relationship Between TBW and SSD Performance How to Choose the Right SSD Conclusion Whether you’re an individual user or a business client, selecting an SSD that matches your workload is a key step toward optimizing your storage experience.  ( 4 min )

Sticking with COBOL instead of migrating to a modern language like C++ can result in missed business opportunities due to limitations in flexibility, scalability, and alignment with current technological trends. While COBOL excels in certain legacy environments, it can hinder innovation and growth in several key areas.

Automate Your Cloud: A Deep Dive into the DigitalOcean API Imagine you're a DevOps engineer at a rapidly growing e-commerce startup. You need to quickly provision servers for a flash sale, scale your database during peak hours, and automatically roll back deployments if something goes wrong.

We can manage, update, restart, and scale each Docker container separately. That's the beauty of containerization. Each container should have a single responsibility. PHP, Java, NodeJS - each of those does one obvious thing. Creating containers that include multiple services is considered an anti-pattern. The Single Responsibility Principle doesn't apply only to our codebase. But does it mean that we must not create such anti-pattern containers just because it violates SRP? I believe there is a one good reason why we can violate it, and let me show you that. Let me describe the problem I encountered.

world war II was raging.  meanwhile two guys - mcculloch and pitts - sat down and asked a weird question: can we describe the brain… using math? we were trying to decode ourselves. they weren't coding. they were dreaming. it didn't do much. it couldn't learn. but it was enough to start a fire. they sparked a new kind of thinking… one where intelligence wasn't magic or soul or mystery… fast forward to 1950s… but nobody could even define "thinking." in the 60s, we tried rule-based logic. in the 80s, we returned to neural nets. in the 2000s, we gave up again. then came 2012. a deep net beat everyone at recognizing cats on the internet. we taught sand to dream in probabilities. we made silicon hallucinate. we layered millions of artificial neurons and whispered billions of words into them. today, we have chatgpt. tomorrow… god knows what. that's why i have created boringskool.  we're not here to predict the future. we're here to trace how we got here… and how to ride the next wave with eyes wide open. our first video is out now. it's not a tutorial. it's a story. the truth is, this isn't just about ai. and then ask yourself: this is the first video i've ever put out. and if you're reading this…  it means the world. seriously. your support right now isn't just clicks or views… it's momentum. it's what keeps this thing going.  boringskool isn't backed by some big team or fancy funding…  so if this video hits something in you… share it, talk about it, reply.  this is just the beginning.  ( 4 min )

— Why Some Benchmarks Miss the Point, and What We Should Really Be Comparing Recently, an article titled “We Threw 1 Million Concurrent Users at Go, Rust, and Node.js” made waves in the webdev world. Its conclusion? Node.js is obsolete. Go and Rust crushed it in a massive load test, with Node dropping connections left and right. At first glance, the results seem compelling: Node.js lagged behind, struggled with memory usage, and had higher response times. But dig deeper, and you’ll realize: This isn’t a case of Node.js being bad — it’s a case of bad testing design.

How a single MacBook trackpad turned my “smooth” calendar into a time‑machine. Trackpads don’t emit smooth, predictable scroll deltas. A single swipe often starts with sharp spikes (e.g. …17, 67, 82…) and transitions into a decelerating phase. But just when it seems to be tapering off—boom—a rogue value can pop up in a sequence such as …17, 15, 13, 26, 12, 11…, throwing off gesture detection. A reliable fix is a two-phase filter: first, ignore all events for ~100ms after a gesture begins; then, during the deceleration phase, compare the last three deltas—not just the current and previous—to ensure values are consistently tapering. This approach prevents unintended jumps. I built a calendar where swiping up/down flips between months. Mouse‑wheel testing felt flawless. Trackpad testing, howe…  ( 6 min )

Today was my first day in Java class at my institute. We started with an introduction to Java and discussed its features. Here is what I understood Java is easy to learn and use. Its syntax is simple compared to C++. It doesn’t have confusing concepts like pointers, so writing code becomes easier. Java is fully object-oriented. Everything in Java is treated as an object. It uses concepts like: Inheritance – using existing class properties in another class Encapsulation – hiding data using private variables and public methods Polymorphism – performing one task in different ways Abstraction – hiding unnecessary details from the user Java is a secure language. It doesn’t use pointers, so no one can access memory directly. It checks the code during both compilation and runtime to avoid any se…  ( 4 min )

Understanding a database starts with understanding its structure. For PostgreSQL users, one of the most effective ways to visualize and manage your schema is by using an Entity-Relationship Diagram (ERD). Either if you're working with a large legacy database or starting something new, an ER diagram shows how your tables are connected and how your data is organized. In this article, I'm using DbSchema - a visual database design tool that’s free to use for creating diagrams. You can also generate HTML5 documentation (up to 12 tables in the free version) and explore features like Git integration with a 15-day trial of the PRO edition.

Keeping string data accurate is a routine but critical part of working with databases. SQL’s REPLACE() function lets you update one string with another directly within your query. Whether it’s correcting typos, rebranding statuses, or rolling over a year reference, REPLACE makes it easy and efficient. Examples of SQL REPLACE in Action Standard syntax: REPLACE(column, 'old_string', 'new_string') Change a year value UPDATE products SET description = REPLACE(description, '2023', '2024') WHERE description LIKE '%2023%'; Update product status UPDATE products SET status = REPLACE(status, 'On Sale', 'Discounted') WHERE status = 'On Sale'; Case-insensitive replacement UPDATE employees SET job_title = REPLACE(LOWER(job_title), 'technician', 'engineer') WHERE LOWER(job_title) LIKE '%technician%'; This ensures consistency regardless of input case. FAQ Can REPLACE work on columns with NULLs? No. If the value is NULL, REPLACE skips it. You can use COALESCE() to default the value and avoid this issue. Yes. Major databases support it, though PostgreSQL users may also explore REGEXP_REPLACE for pattern replacements. Use nested functions: REPLACE(REPLACE(column, 'old1', 'new1'), 'old2', 'new2') Yes. You'll need to convert to lowercase or uppercase manually if you want to ensure a match regardless of case. Conclusion SQL REPLACE() is a simple but highly effective way to keep text data accurate and clean. From handling simple find-and-replace operations to transforming columns during updates, it’s a tool every SQL developer should know. To explore its nuances across platforms like PostgreSQL, MySQL, and SQL Server: Read the full REPLACE guide: SQL REPLACE Function: A Comprehensive Guide.  ( 18 min )

🔄 Understanding Interactive Transactions in Prisma Interactive transactions in Prisma allow you to execute multiple queries in sequence so that either all succeed or none do. This ensures atomicity, a key part of the ACID principles meaning either the whole transaction happens or nothing happens at all. In Prisma, you can use interactive transactions via prisma.$transaction(async (tx) => { ... }). The tx object is a special TransactionClient, passed to all queries inside the function, and it ensures that they run within the same transaction context. const result = await prisma.$transaction(async (tx) => { const user = await tx.user.create({ data: { name: "John", email: "john@example.com" } }); const profile = await tx.profile.create({ data: { userId: user.id, bio: "Softwa…  ( 5 min )

Your company has data. Sales reports, customer analytics, marketing metrics, website traffic. You've invested in tools - dashboards, warehouses, BI platforms. Yet, decisions still feel like guesswork. One team claims revenue is soaring. Another says it's stagnant. Marketing celebrates a campaign's success, but finance disagrees. Everyone's working with data, but no one's on the same page. Why? Your data isn't the problem. How you manage it is. Most companies drown in disorganized, untrusted data that creates more confusion than clarity. The solution isn't another tool. It's a data platform  -  a system to make your data reliable, accessible, and actionable. Here's how it works and why it's critical for your business. When data isn't managed well, it doesn't just slow you down - it costs yo…  ( 6 min )

Part of my series on contribution to Open Source project. Moodle is web-based open source learning platform aka. Learning Management System (LMS) written in PHP. I also encountered it at Azrieli College of Engineering in Jerusalem when I taught the Open Source Development Course in a semester. One of the difficulties with such as application is that when you encounter a problem or when you miss some functionality you don't know why. It is unclear if the problem you encounter is due to the decision of the local admins, due to using an old version of Moodle, or a real issue with that you also have in the development version of Moodle. So you don't know if you need to ask the local admins to change the configuration or you need to ask them to upgrade the version of Moodle or someone really n…  ( 4 min )

If you follow me, you may know that I've been a web developer for over 5 years. To be more precise, I started my career as a web developer and have built multiple websites in different categories for my clients and as an employee. Earlier, there was no ChatGPT or Gemini to help, so I had to write each and every line of code by myself, which was too tedious. Fast forward to today, we have ChatGPT and similar LLM tools to help you with literally every task. And now, I was thinking of building a blog website for myself which I have full control over, can rank on Google, and for more reasons. So I went to ChatGPT and started my research to build a blog website for me. Since I'm a web developer, I have the expertise to ask ChatGPT clearly about what I want and even build a blog myself.

Ok let me get straight to the point — I've been working as a technical writer for a while now, and if you're thinking of getting into it, I'll give you a quick rundown of what you'll actually need — not just the stuff they mention in job descriptions. No, you don’t have to be a senior developer. But you do need to understand how things work. You should be comfortable reading documentation, looking at code, and maybe even running the software locally. Forget flowery language. The goal is clarity. Think: “Click this button” “Run this command” “Here’s what happens next” If a beginner can’t follow your writing, it’s not done yet. You’ll often document features that aren’t fully built or explained. Don’t be afraid to ask developers: “What does this return?” “What’s the default behavior?” “What happens if it fails?” You’re not bothering them — you’re making sure users don’t have to. You’ll likely write in Markdown and push docs to GitHub or GitLab. git status git pull git add . git commit -m \“Update docs\” git push You’ll deal with multiple files, folders, edits, reviews, changelogs, deadlines — all at once. Being a technical writer is about bridging the gap between the builder and the user. You don’t need to know everything, but you do need to be curious, clear, and collaborative. If that sounds like you, you’re already on the right path.  ( 4 min )

Terraform Comprehend: Managing AWS Comprehend with Infrastructure as Code Infrastructure teams face a recurring challenge: integrating natural language processing (NLP) capabilities into applications without creating operational overhead. Traditionally, this meant manual configuration of AWS Comprehend, managing API keys, and building custom deployment pipelines. This is error-prone, non-repeatable, and hinders scalability. Terraform’s ability to codify and automate infrastructure provides a solution, but requires a deep understanding of the service and its integration points. Comprehend, in this context, isn’t a Terraform-specific service, but rather the management of AWS Comprehend resources through Terraform.

Introduction Getting ready for a JavaScript interview? Asynchronous JavaScript interview questions are everywhere in technical interviews. Don’t worry – this guide covers everything you need to know about asynchronous JavaScript, from basic concepts to tricky interview scenarios. Here’s something that confuses many developers: JavaScript is single-threaded, but it can handle multiple tasks at once. How does this work? The secret lies in how JavaScript engines work with browsers. While JavaScript itself runs on one thread, browsers provide extra tools that make async operations possible. Think of the call stack as a stack of plates. When we call a function, it goes on top of the stack. When the function finishes, it gets removed from the top. Basically call stack is where JavaScript keeps…  ( 5 min )

In real-world scheduling scenarios, there's often flexibility in meeting times. LeetCode 3440 explores a variation where you're allowed to reschedule one meeting to potentially maximize your continuous free time during a larger event. Unlike its predecessor, the relative order of meetings can now be changed. This introduces an interesting optimization problem that mixes greedy scanning with intelligent rescheduling. You are given: An integer eventTime, representing the full span of the event (from t = 0 to t = eventTime). Two arrays: startTime[] and endTime[], where each pair defines the start and end times of n non-overlapping meetings. You can reschedule at most one meeting (by changing its start time but keeping its duration the same), as long as: The new time doesn't exceed event bound…  ( 5 min )

Creating complex objects, like a custom Car, often involves juggling multiple attributes: engine, wheels, color, etc. Using a single constructor with many parameters is cumbersome and error-prone. How can we build such objects cleanly and flexibly? The Builder Design Pattern in Java provides a solution by separating the construction process from the object's representation, enabling step-by-step assembly. The Builder Pattern is a creational design pattern that constructs complex objects incrementally using a dedicated Builder class. This approach improves code readability, supports flexible configurations, and avoids bloated constructors. Below is a Java implementation of the Builder Pattern for building a car object: Create Car class. public class Car { private String engine; pri…  ( 4 min )

Encryption keystrings are critical components in protecting digital information. Whether securing device communication, authenticating users, or safeguarding sensitive data, a well-designed app must generate strong, reliable keystrings to meet modern security standards. The process of generating these keystrings involves cryptographic best practices, strict randomness, and secure system integration, as implemented in the Device Keystring App. At the core of keystring generation is randomness. To ensure that keys cannot be predicted or replicated, the app uses a cryptographically secure random number generator (CSPRNG). Unlike basic random functions, a CSPRNG sources entropy from secure hardware components—such as the device’s Trusted Execution Environment (TEE) or Secure Enclave—to produce…  ( 4 min )

Most beginners think “database” just means “a place to store data.” But a real relational database is designed to handle way more than that, correctness, consistency, and efficient querying at scale. When you use a proper SQL database, you get: ACID properties (Atomicity, Consistency, Isolation, Durability): you don’t want to half-update a payment or lose data after a crash. Joins: data in the real world is related. Users have orders, orders have products, etc. You can join tables instead of duplicating data everywhere. Indexes: searching without indexes is like scanning every page of a book to find a word. With indexes (B-Tree or others), you get faster lookups. Data integrity: foreign keys, constraints, and types prevent accidental or corrupt data. Normalization reduces duplication and e…  ( 4 min )
